[plt-scheme] windows aborts Drscheme

Hi,
Windows sometimes aborts DrScheme while running, particularly when I 
concurrently use other applications. This may be a problem within my system, 
but if anyone has seen the same thing, please let me know and may be you can 
tell me how to avoid the problem.

I use DrScheme, version full 369.5-svn17jan2007, english (installed by 
full-369.5-bin-i386-win32.exe) with Microsoft Windows XP, Home Edition, 
Version 2002, Service Pack 2. I run the program by opening the scm file and 
pressing the run button. I never saw this problem in previous versions of 
DrScheme. If you need more details, let me know, please.

Greetings, Jos koot
