Which games are you playing which are showing this issue?

Would really like an answer to this! It is still happening I'm afraid  

If there is any more info on this I would appreciate it! =D

It would not surprise me if this was the case. 

Nonetheless, does anyone know of any solution to this problem? 

Every time I have to do stuff on the other pc I have to tab out of the game or go into the menu, so the character doesn't do stuff like shoot every I press the mouse button. Or move around when I use the mouse...

Thanks for the answers even if they were not the solution!! Every answer helps

Could you provide a specific example of games which have the issue so we can try to reproduce it here?

I suspect they are all 64 bit as MP has a system to stop this kind of thing but it only impacts 32 bit processes.

Install the beta build from here : https://forums.stardock.com/510351/page/3/#3842229

Thats reply 56 if the direct link doesn't work right.

Yes, a clean boot, on each PC, detailed here:

I have little doubt it will expose that another app \ setting is causing your issue.

This was resolved for everquest in an optional Multiplicity update.

Nevermind:  I am the paying customer but I will do it for you so people have a consolidated support answer

- First off if your mouse is repeating on satellites make sure you have installed version 3.57 J68
The download for that is here: https://cdn.stardock.us/support/uploads/Multiplicity_3.57-j68-Setup.exe

- You must make sure that it is installed on all machines. 
   - Just a note your version will say Version 3.57 Build 00104.kvm on the primary but for some reason shows version3.58 build 00104 on the  satellite/secondary computers

Ensure you do a fresh restart on each machine after you finish the installation and before you set it up

If it is working now great, otherwise you have a program interfering with it.  And if it stopped it was probably a recent update. For instance the most recent version of Teams being installed on my computer caused it to break again.   You can figure out what is causing the issue by doing a clean boot, (booting with nothing but windows services) and then enabling programs one at a time.  At least until they decide to do enough work to actually find out why its breaking and fix it, instead of asking us to spend hours troubleshooting the software we bought, this has always been a solution that worked for me.  However, you can't update or use that program and Multiplicity ever again. 

Some people have had luck with Windows 11 fixing the issue by going to the program folder, and selecting properties on the exe and telling it to run in compatibility mode for Windows 7.   This also has worked for me until a windows update broke it again.

Other people have had good luck creating a windows profile just for gaming that they can log into, however doing this has still caused it to break for me whenever software installed on other users is updated.

This is has nothing to do with updates from Everquest.   It is frustrating that you commented like that without actually reading and understanding what was said.

Your software repeats this errant behavior no mater the program on the primary that is open that has focus.   From CAD to any game or software that is in full screen, the mouse mirrors movement on the primary with right mouse held while on the secondary computers.

Any program
Go ahead and re-read that above sentence.

If you had actually read the post, you would see that other programs updates are causing the issue, not Everquest.   The last one was the Microsoft Teams update on 8/1.   You can also see that I didn't mention Everquest once, because as I have posted before, I use your software for more than just gaming.

I personally believe just mostly visible to you with Everquest customers because it is a popular game that uses the right mouse held for movement on secondary screens. and benefits from the features of your software. 

To me this errant behavior cropping up again with certain third party updates points to a part of windows that these pieces of software jointly use, but I don't know enough about your software to fix or isolate it.   Not my onus.  What I can do and did was share the solutions with your customers that have been working for me.    Something you should have done instead of pointing your customers to a 200 locked thread that they would have to spend an hour or more filtering through, and still may miss what worked for people.

The issue returned when  I reinstalled Teams, its a daily driver I cant be without.  However I went back and set compatibility mode to windows 7 again and resolved.  Something to do with my Windows 11 maybe?

I use 5 other machines with my primary, and none of the others have teams, it was only installed on the primary.  So I dont know.

Example of a workflow outside a game that it happens

Primary.  Unreal Engine 5 + various pluggins
Secondary:  Blender with various plugins
Tertiary: Photoshop
fourth and fifth random third party tools depending on what I am doing,

Neat setup with your software, allows me to utilize different processors rather than multiple process tying up my GPU/CPU/Ram and works with shared assets networked on the primary.   Not to mention the clutch copy/paste

But you rightmouse on any other machine it is selecting assets or moving on the primary.

Also I know you make games, I own all of them.

PS.  Sins of a Solar Empire 2 or a remastered of 1 with 64bit full memory/texture support plz!
