javaw Slowdown

This is a new problem. I have slowdowns in WDSC when editing an RPG
member. WDSC basically 'locks up' for a period of time, like 10-20
seconds. Looking at Task Manager shows the javaw.exe process consuming
98%+ of the CPU. I'm just doing normal editing tasks when this happens,
like arrow key movement. I'm running Version: 5.1.2.6, Build id:
20051002_2139. This problem has just started, and I can't think of
anything that's changed (famous last words<s>). 

It's getting kinda frustrating...I'm thinking of using SEU again, but
WDSC really helps with a large program. I've rebooted (warm and cold)
and the problem persists.

Any ideas? TIA...
