Doom 2 : absolutely no problems! BUT:
Doom 1: Whenever I run into a suit, a 200% health ball or the spectacles, it crashes. This is later very annoying since in certain levels, you cannot cross the path withut walking over them

Is there an easy explanation for it? I´m using the very same wad-file that has been working so well in 16 years of PC-gaming, and otherwise there is no prblems.
Thank you for your answers..
