Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.2b) Gecko/20021016 Using default theme. Reproducible-always. 1. Start Mozilla. 2. Click File (or any other) main menu item. 3. Wait ~0.5 sec (do not move mouse!) 4. Click File again 5. Wait ~0.5 sec (do not move mouse!) 6. Click File again Result: "File" menu item border is not in "lowered" state, as if there is no mouse on it. Expect: item border "lowered", because the menu is opened. Additional: after moving mouse a bit, item displays normally; clicking on menu without waiting cannot reproduce a bug(!). I think this bug can be related with bug 163704.
Find a duplicate please.
