I'm running Windows 2000 5.00.2072 and using Visual C++ 6.0. Just lately I've noticed that the Visual C++ UI seems to "flicker": the mouse changes from a pointer to a hourglass for an instant at about 1 second intervals, and the list of files in the project seems to be redrawn at the same time. I've tried stopping all other processes that I could stop with no effect, and only MSDEV seems to be using any CPU time. This only happens during the code editing phase, and only with one workspace, which is a COM object. So I'm pretty sure that the problem is in Visual Studio. Any ideas on what could be causing this annoying behavior?
