srpwnd: Just published another update that should fix this. It should be rolling out to you right now.
In case there are any other problems let me know.
The recent update broke the full screen functionality. The game now always starts in a window. When full screen is selected from the options, the window is small and in the center. If I disable full screen and restart, the window becomes bigger and it's not centered anymore, it's top left corner starts in the center of the screen and the rest of it expands beyond the bottom right corner of the screen.
Verify & Repair didn't change this. GOG says the version is still 2.5.6, the same one that broke it a day or two ago.
I also have a bunch of minor UI bugs to report, unless this update fixed all of them. Do you have preferred ways for reporting non-critical bugs?
