I just started porting my quite old game project from AGS 3.4 to 3.6b3.
It already compiles, but crashes with the following exception.
Since I replaced a lot of Viewports and System.ScreenHeights, I can't exactly tell you, what did cause this crash.
An exception 0xC0000094 occurred in ACWIN.EXE at EIP = 0x0050A95E; program pointer is +373, ACI version 3.6.0.23, gtags (663,20)
I hope it still somewhat helps.
