By the way, do you know how the fix used in the GOG version exactly works?
If I find out the principle of its work, maybe then I can understand why the game freezes after mouse clicks.
It seems to me that GOGLauncher.exe simply fills the entire screen with black color, then launches KILLTIME.EXE and it somehow fixes the messed up colors. I don't understand how such a simple fix can cause any problems.
Despite the fact that the Zoom Platform version works great for me, I'm still more interested in the GOG version.
*** It would also be nice if GOG staff finally showed up to say something over the past two years.
