Julien,
I've never implemented a debugger so the best I can do, when no one else
seems to be providing help, is suggest something based on the problem
description (an explicit selection updates the buttons that otherwise
don't update). If that doesn't help, there's really nothing else I can
suggest. Hopefully someone else will suggest something...

All I can suggest is to make sure that you are you firing debug events
appropriately when you step, resume, hit a breakpoint, etc. If you are
stepping, I think you need to do something like:
- fire DebugEvent.RESUME event with
DebugEvent.STEP_INTO/DebugEvent.STEP_OVER detail
- perform the step in the physical debugger
- fire DebugEvent.SUSPEND event with DebugEvent.STEP_END detail
I think it is the SUSPEND event that will attempt to select your stack
frame and re-enable the step buttons. Of course, you need to make sure
that your debug elements (DebugTarget, StackFrame, etc.) also report their
state appropriately in terms of isSuspended, canStepInto, etc.
Mark.
