I commonly open several instances of Visual Studio at once (many client and server applications). I will be double clicking on several solutions in a row and then allowing them all to load, more than 50% of the time that I do this some of the last solutions to load will have reset to the default settings.I can see this clearly as my settings involve spreading the various tool windows across my second monitor, but when the settings are lost I am back to a single monitor view.If open the same VS solutions one by one (waiting until the loading projects 1/N screen appears) then I never see this problem.
Visual Studio/Team Foundation Server/.NET Framework Tooling Version
