I'm trying to find global usages of classes and methods, using Ctrl-Alt-F7 when the cursor is on the method or class name, and it is telling me "No usages found in Project Files" every time, for everything - even for methods that are clearly used within the same class...
This is really bad news when I'm deep into debugging an application.
The log shows nothing. However, if I use the context menu (right-click) or Alt-F7 'Find Usages' and search the whole project, the search works OK, and I then the Ctrl-Alt-F7 global 'Find Usages' starts working again.
Needless to say, this is extremely disconcerting.
