Periodically, my VS05 IDE will max out the CPU and just seem to hang. Terminating the IDE and restarting doesn’t seem to fix it. What I have found is that there would appear to be something being stored in the pdb that has to do with the breakpoints. The reason I say that is when this situation occurrs, I can work around it by deleting all of my breakpoints, closing my windows and then trying to run with a fresh build. We already know that somtimes the VS05 IDE window manager can take the IDE out to lunch, but I don’t think this is related.
