Main Menu applet: un-selectable menu items on menus that are larger than the screen height

[Sameer Morar]

Binary package hint: gnome-applets

Description: Ubuntu lucid (development branch)
Release: 10.04
gnome-applets:
  Installed: 2.30.0-0ubuntu1
  Candidate: 2.30.0-0ubuntu1

Steps to reproduce:

1) Right click on a free area in the panel and choose "Add to panel..."
2) Select "Main Menu" (NOT Menu Bar!!), and click Add
3) Click on the Main Menu Icon, and locate the longest menu (probably System->Preferences)
4) Resize screen resolution to ensure that the longest menu does not fit in the screen
5) Try to launch any item on the menu below the scroll area

What happens:
When the mouse enters the scroll area, the menu scrolls down.
However, when the mouse leaves the scroll area, the menu scrolls up, and the last visible menu item (without any scrolling) is highlighted.
It appears to be impossible to launch menu items below the scroll area using the mouse.

What is meant to happen:
When the mouse leaves the scroll area, the menu should not scroll up, and visible menu items should be highlighted by the mouse.

It is possible to select these menu items using the keyboard, so the bug appears to be something to do with the mouse leaving the scroll area.

This bug is not present in the Menu Bar applet. Thus, the behaviour in the menu bar applet should be copied to the Main Menu applet.

This bug has a large impact on netbook users that are not using the netbook remix ui, due to the low vertical resolution resulting in scrolling menus, and the need to replace the Menu Bar with the Main Menu applet to conserve space on the panel.
