Debugger settings getting lost

1. Go to "Tools" -> "Options..." -> "Build & Run" -> "Debuggers".
2. Make sure you have at least two debuggers set up.
3. Click on one of the debugger settings and change its name or path.
4. Click on a different debugger setting.
5. Click on the setting from step 3 again.
   Your changes are lost.

The changes should not be dismissed until the user clicks "Cancel". See how other tabs of "Build & Run" handle this situation.
