>Description:
I'm running Insight version 5.1 under Cygwin. If I embed an int 3 instruction in my code and I my program gets to the int 3, a Warning dialog box with the message: 
 
 Program received signal SIGTRAP, Trace/breakpoint trap
 
pops up. This is fine and if I click on the Ok button the dialog box goes away as expected, however, if I hit return to dismiss the diaglog box, a GDB Error dialog box with the message: 
 
 Error: can't resolve scoped variable "@itcl ::.warningdlg0.warningdlg ::ModalDialog::unpost_notification": can't find object ::.warningdlg0.warningdlg
 
pops up and if I click on the Stack trace button I get:
 
Stack trace shows:
 
 can't resolve scoped variable "@itcl ::.warningdlg0.warningdlg ::ModalDialog::unpost_notification": can't find object ::.warningdlg0.warningdlg
     while executing
 "set {@itcl ::.warningdlg0.warningdlg ::ModalDialog::unpost_notification} 1"
     ("after" script)errorCode is NONE

 Ok, I think I've figured this out. ModalDialog::unpost was being called
 twice for the WarningDialog. <Return> in the warning dialog was bound to
 invoke the button. But the button is the only button (and starts with the
 focus), so it was being invoked via a default binding.
 
 I've "fixed" this by having <Return> not run any other bindings. This
 doesn't seem to affect current trunk sources, so I am not going to check
 anything in there.
 
 Apply this patch in src/gdb/gdbtk and re-install gdb. Please let me know
 if this fixes the problem for you.
