--- Comment #24 from Bruni earns.61@gmail.com 2011-06-22 13:25:36 CDT --- 1.3.22 - still present, but the game runs a little faster than in previous versions. I guess this bug depends on implementation of 32 bit bitmaps, which have the property of being transparent. If Huw adds this in 1.3.23, the bug will be fixed (in my view).
