I have a swing application with lotf of menus/sub-menus added to the menubar. I am clicking on one of the menus and opening upto 2 levels of menu. Keeping the menu shown, I am pressing 'ALT' and down arrow. This brings up Frame's menu. I am choosing the 'MOVE' option from Frame's menu through keyboard. Now I am trying to move the frame using ARROW keys and the frame moves. But this does not make the swing menu disappear and they are still shown in the old place.

This is a regression introduced in Mustang-b52/b53 since this passes with Mustang-b51 on WinXP. On previous builds/releases, the swing menu disappears as soon as I start moving the frame using arrow keys.

Run the attached test. Choose 'GO' -> 'prev' -> one of menus listed under 'prev'. Press the ALT key and down arrow. Frame's menu will come up. Select 'move' option. Now the cursor will change to move cursor. Press the arrow keys and move the frame. If swing menu still stays at the same position without disappearing, the bug is reproduced.
