problems with XFree

Harold, thanks for the suggestions.  I was hoping that oue of them would 
solve the problem.  I checked and found only one cygwin1.dll on the 
system.  It's dated 5 July.  I update frequently using setup.exe.

I agree with you assessment of Windows.  However, my problem isn't the 
BSOD but XFree86 seg fault.  Windows keeps on working and the (apparent) 
memory leak resolves itself after CFree86 croaks.

Let me know if there is anything else I can do on my end to identify the 
problem.

Thanks,
Tom
