Heavy slow down and disconnections.

[NightfallGemini]

During game play, the lobby will disconnect with "Server sent ambiguous command!", and my entire computer will slow to a crawl, quite literally, until I kill the processes of Spring itself and the lobby.

I'm currently running it in windowed mode, 900x700.

My computers stats are:

AMD Athlon XP 2000+ (1.67GHz according to windows, 2.0GHz according to Spring)
Radeon 9200 128MB DDR
512MB DDR RAM (No-Name)
EliteGroup LV7MM motherboard
160GB Western Digital Caviar SE
Windows XP Home Edition Service Pack 2

Also, not sure if this would matter, but my internet connection is 1.5Mbit (150 to 165KByte a second down, 40KByte up).

When I open the task manager, I'll notice Spring and the lobby are using no CPU according to the task manager, but the CPU usage meter at the bottom of the screen will go from 0% to 100%.

It's happened during play using BOTA 1.2 and XTA Pimped Edition. Haven't tried it with Final Frontier or SWTA Spring yet.

EDIT: After testing it a bit with a few different mods, I've found that it does it regardless of whether I'm against the AI or not! Also, I've noticed wowexec.exe and ntvdm.exe running in the background..

Aren't those for old old old apps?

Circled in red are the processes that don't normally run at all. Circled in black are ones that normally use just about no resources. Also take note of Spring using no resources when it SHOULD be using atleast 90%.
