[gnome] Netbeans 7.2 problem with menus when using mouse

view story

http://ubuntuforums.org – I'm using Mint 13 (cinnamon)and when netbeans 7.2 (Installed from source from website) is maximized or enlarged by dragging. The top menus (file, edit etc) do not work properly with mouse as in they do not stay open on mouse click. But works fine with keyboard. Its also works if the windows is not enlarged or not maximized. I found a bug report but don't know how to apply the patch. http://netbeans.org/bugzilla/show_bug.cgi?id=198639 Please help. (Hardware)
