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,
--

The terminal services server is not installed on Win2k Pro and XP. The
client can be but I don't think that would interfere with IDL. Terminal
services are installed by default (?) on Win2k Server and Advanced Server.
I don't know about NT4. They can be removed by using the install cd.
