I recently updated to 15.0.1 and I'm unable to use it. When I load a Visual Studio 2005 Solution file into it to work on my project, it just sits there and consumes 100% CPU. I can get about one character into the window every minute.
If I unload the project (which is an extremely difficult process since it takes several minutes to open the Project menu so i can go "Close Workspace") things seem ok and I can use the menus again.
15.0.0 does not suffer from this problem. Is there something I can do to help diagnose the issue?
