Problem with .Net app using 25% cpu

Hi!

I am developing a .Net app and I have got some problems with the program
suddenly using 25% cpu... The strange thing is that my program is not doing
anything(as far as I can tell), and the UI is just as responsive as ever,
even though it's single threaded (shouldn't it get a little sluggish??),
leading me to believe the problem must lie in a thread I don't controll
(GC????) . The program will keep using 25% cpu until shutdown, when restarted
it can work satisfactory (about 1-2% cpu) for anything between 10 minutes to
10 hours before the problem reappears.

Using a process viewer I have found the faulting thread to be spending time
in
mscorwks.dll!ReleaseFusionInterface, anyone know what this is???

Any help would be greatly appreciated

can you reproduce this problem thru a small sample program?

Very difficult because I have absolutely no idea what causes this behavior,
it's a pretty simple, straightforward app, no threading etc. I even have
another app that is almost 99% similar, and it functions flawlessly....
