I upgraded from Multiplicity 3.6 to 4 Pro (Beta). The upgrade went surprisingly smoothly, though I did have to re-install on the primary PC to make it accept settings changes.
Everything appears to be working perfectly now except for an odd glitch when transitioning between two PCs in the Advanced resolution aware grid Seamless mode:

- When moving the mouse from "WIN-4BI SSQE1DI..." DOWN to "DESKTOP-Q5...", the mouse snaps to the upper left corner of "DESKTOP-Q5..." instead of being at the correct horizontal location along the top edge of "DESKTOP-Q5...".
- When moving the mouse from "DESKTOP-Q5..." UP to "WIN-4BI SSQE1DI...", the mouse snaps to the lower left corner of "WIN-4BI SSQE1DI..." instead of being at the correct horizontal location along the bottom edge of "WIN-4BI SSQE1DI...".
All mouse transitions to and from those two PCs and the primary monitors on the right are perfect.
- It would be nice if I could manually edit the XY offsets of the screens as in the old mode. Dragging the screens is a little coarse. But, this interface is so slick I am 95% happy anyway.
Thank you!
