Summary	09500: Debugger crashes after hard reset with the marker on the disassembly view
Description	Debugger crashes after hard reset "key" (Shift + F3) if the marker is active on the disassmebly view. No problem with hard reset "command" because of out of focus.
Steps To Reproduce	1) Execute MAME with debugger 2) Press tab key (or click disassembly view) in the main debugger window 3) Confirm that the marker is active on the disassmbley view 4) Press Shift + F3 to hard reset
