Hi Liam,

Well, it turns out it was on Windows 2000 Advanced Server. Terminal
Services are only available on Server versions. I'm running Windows 2000
Pro, and to check, I open Add/Remove Programs, click Add/Remove Windows
Components: Terminal Services is not available anywhere, so I'm safe
from this one!

I have had large-pixmap allocation problems in the past as well, and
everything made more sense when I realized that (just like in the RAM
discussion "Memory Headaches" from August 2002) a pixmap needs a
*contiguous* chunk of video memory.

I would love to find a utility program to show how Windows memory
(including video memory) is being used... anyone? This dandy little Mac
program gives the idea, does such a thing exist for Windows?

Cheers,
