2. Deskcapes version number.

Thank you.

I tested on the same Windows 10 version and OS Build as yours. But, I can add files to that folder and it get display when their turn come.

Here is my steps in testing this.

1. Create a new playlist.
2. Add few background, just to make it easy, I add two background to that playlist.
3. Add folder->Add folder contents and update for changes automatically->Select a folder with 2 background.
4. For fast testing: Click on settings->change timing to 1 minute. sequential selected.
5. Apply playlist.
6. Watch the playlist get play. Close Deskscape config window.
7. As it get play open up that background folder. Add two new background into that folder.
8. Watch and see the new background appear.

Thank you,

I am sorry I forget this important information. My playlist content is all mp4. Do your test with all mp4 content. thank you.

I do your steps. No update happens

Here is a link to my test folder :

https://we.tl/t-ccfCUoTBDX

It contains 4 short mp4s. Please run your test with these -thx 

ok, thank you. I will wait on the Support Team's response.

I went thru these 'purge' steps previously for a different issue and it did fix that issue, I also have seen other topic issues where this 'purge[ is advised.

This is unsettling because it informs me that this software has a stability issue. However, thankfully, my issues have not, so far, been showstoppers.

-thx
