Hi guys,
This is unusual but I'm experiencing a crash and I'm looking for help
or insight in tracking it down. I haven't been able to reduce it to a
simple case and I'm not sure what to make of the stack trace. Any
advice would be appreciated so I can either report it or fix it in my
code.
This used to work in previous versions of RB, but half the time I get
a freeze for about 10 seconds then a crash with RB 2006r4. This is on
Mac OS X. The stack trace is below.
Exception: EXC_BAD_ACCESS (0x0001)
Codes: KERN_PROTECTION_FAILURE (0x0002) at 0x00000000
Thread 0 Crashed:

What this code does is show a contextual menu when the user clicks in
a cell in a listbox. The contextual menu is a ContextualMenu control.
I don't use the newer events because the contextual menu is shown on
a normal click, not on a right-click. It's basically used as a popup,
exactly like the listbox of the constant editor in RB itself.
I repopulate the popup every time before it is shown to populate it
with values appropriate for the cell the user clicked on. This is
what the method OpenLabelPopup in the trace above does. It calls
LocalizedLabelText to get a localized string. This is a one line
method as shown below:
Function LocalizedLabelText(Label as String) as String
return App.Language.Text(Label)
End
Problem is, I don't know how this line relates to the rest of the
stack trace which goes off into the RB framework. Any ideas where the
problem is or how I can isolate it?
You can try the app yourself if you want:

Thanks for any help,
