A: 

I have been unable to reliably reproduce the error, but it seems to happen when the number of files in the project reaches a certain level. A workaround I found is to disable sourcecontrol before loading the project and loading the sourcecontrol AddIn after all files are present in the IDE.

I recently found the comfort of *not* loading Source Control plug-in at all. I'm using VSS explorer now (trying to migrate to TFS) and the IDE is much more stable and somewhat faster. Most convenient thing is that I can now edit read-only files at run-time, checking them out later. More goodness, MZ-Tools can be configured to use a shortcut (Ctrl+Shift+S at my place) to save a modified file at run-time. This alone saves hours in project restart time!
