In VS2012 Update 1 while in debug session if I press stop then the editor is showing a blank page and cannot do any edit. This happens every time. The workaround is to close all documents then reopen the one I want to edit and apply the fix. This is critical as this decreases productivity with 50% or more. Imagine doing this for my all 10 open files while you don't remember what was open. Ofter after the refresh problem there is a crash that follows.
