I have written an application with 5 menus on the MenuBar. Each of the menus is having 2/3 sub-menus and each of the sub-menus is having a few menuitems. I am clicking on a Menu. Menu drops-down. I have 4 sub-menus in this menu. I am clicking on the first sub-menu. All the menu items in the sub menu are shown. Now without clicking anything, I am clicking on another sub-menu. Instead of showing the menu-items in this submenu, the menu itself gets disposed.

This is reproducible on Linux by default, and on Solaris when executing with XToolkit. This is reproducible only on Tiger. This works fine on Motif and win32.

I have attached a sample test. Execute the sample test. You would see a frame with 5 menus. Click on 'Messages' menu. You would see 4 sub-menus. Click on the first sub-menu - 'Move'. You would see the menu items. Now without selecting anything, click on the second sub-menu - 'Copy'. Instead of showing the menu items for 'copy' the 'messages' menu will dis-appear.

This makes the user's job difficult especially when menus contain lot of sub-menus. The user has to click on the menu everytime to traverse through all the sub-menus.
