the menu's lower edge; the menu loses mouse focus.

I think it's safe to say that it's a bug. What seems to be happening
is that there are a number of sub-menus near the bottom of that menu;
when the mouse leaves the last menu item but fails to transfer to its
sub-menu, the hand loses focus on the original menu.

Note that the menu is still completely functional; even though it's no
longer tracking the mouse, you can still use the mouse to click an
item.

The bug seems to be in MenuItemMorph>>deselectTimeOut:, which sets the
mouse focus to nil. Does changing that from nil to owner do what you
want?

  deselectTimeOut: evt
    "Deselect timout. Now really deselect"
    owner selectedItem == self
        ifTrue:[
            evt hand newMouseFocus: owner.
            owner selectItem: nil event: evt].

Here's the bug report I've put on Mantis:

Hope this helps!
