Sofar you are the only user reporting this behavior. The MVC solution was not developed with the tools you are mentioning (Resharper, etc), so none of these 3rd party files exist in the solution folder.
I assume you are using Resharper and Visual SVN? Resharper in particular does a lot of background processing and this could possibly explain the long waits?
In a few instances I have noticed something similar which seems to be related to the keyboard shortcut bindings. However, the delays are not as severe as you reported. In my case, the bindings are subsequently messed up and the only way out is to restart VS.
Perhaps anyone else on this forum can shine a light on Stephen's issue?
