Roller Coaster Tycoon 2 problems

Archived from groups: microsoft.public.games (More info?)

I recently installed Roller Coaster Tycoon 2 on my Windows 98 computer. The
first few days it was fine, but then it started to act up. A few examples
are that it would randomly close, when maximized it would appear in red and
black, and would close when I go to turn up the volume. However, on my other
Windows 98 computer, it works fine. Is there a possibility of it being a
virus on the computer?
