Sounds like ani issue with compiling? after all it hangs in the compiler-dialog, if I understand correctly?
That's, way before debugging.
You say "if you click all it does is a beep".
That sounds like an other modal form, somewhere preventing the rest of the IDE from reacting.
It may be that there was a crash, and the crash-dialog is hidden behind the compiler form, or similar...
Normally i would say to start with debug-log, or even debug the IDE, to find what it is.
But at current I would simply suggest to upgrade to a 0.9.29 snapshot.
