Crashes with CVS and MSDEV

Hello all.

I work on a very big project using MS Visual C++ 6 and our source control is
done by CVS.
Since a few weeks, we have more and more MSDEV crashes (at least 3 per
hour), and I think that CVS may be a cause of that.
Does anybody her had such a problem ?
Our machines are very clean, under windows 2000 Pro.
The problem is present even on a new installed machine (only MSDEV and
WinCVS)

Can someone help me ?
Thank you in advance and sorry for my poor english, I'm french...

Nicolas.
