The latest version of WindowFX seems to have solved the two issues I had with the program and Windows 10. One odd bug seems to persist, however.
I also have WindowBlinds 10 on my computer. I excluded Firefox and DAZ Studio from being skinned due to a few graphical glitches I was getting with windows not opening correctly, and dialog boxes slowly drifting to the right and down from saving files or even DAZ's file loading notifications. For some odd reason, this exclusion seems to be picked up by WindowFX, and both programs use the standard OS animations for menus or minimizing/closing their windows and dialog boxes.
I checked the exclusion list in WindowFX and it is empty, as I have not excluded any programs from it, so WindowFX most likely is reading it from wherever WB10 saves its own list and using it.
