XnView Software

In Tools | Settings | Fullscreen make sure that 'Show Toolbar' is checked.

Steps:
1. Open Full Screen mode (press F11)
2. Right-click on the Full Screen toolbar
3. Chose 'Customize toolbar'

Expected: The correct page from Tools | Settings dialog should appear.

Actual: The XnViewMP just 'disappears'.

The same thing happens when viewing an image in a non-fullscreen window,
and right clicking on either the menu bar (file, edit etc..) or the button toolbar
and choosing "customize toolbar...".
