Sometimes, if I really do a lot of playing around on some of my sites 
(lots of zooming, panning, printing, etc) I get some 
problems....dllhost.exe starts taking more and more CPU %. After a few 
minutes, it gets up to 100%. If I kill the process, all's well.

After looking at it with Sysinternals Process Explorer, it seems that 
the culprits are actually proj.dll and MgGeometry.dll. Now, I have no 
idea what this means, but here's what Process Explorer has to say about it:

the CSwitch Deta number is really high - 1000-4000
The 2 threads at fault are:

Anyone have any suggestions? This is happening on Windows 2000 Server, 
IIS5 installation with MGOS 2.0.2. It's been doing this off and on, 
fairly rarely for a while now - so I'm not sure which version this 
started at....though I'd wager 2.x.
