This happens a lot, and I'm not sure what's triggering it. I'll start an application, work for a while and everything is fine. If I'm viewing a class or a component, F11 will run the application with the debugger. Then "???" happens and F11 only works when I'm viewing the main application file. I can select the debug profile from the drop-down menu under the debug button, but the shortcut key and the main button no longer function when viewing any other file.
('Run' fails in the same way)
It's a real drag on my workflow to have to flip back to the main app file to launch the application, how do I fix this / what did I do to cause it?
