My menus have not been working since last night. For example if I press start button the box opens up but it is just blank with nothing to select. Same with the edit desktop menu, status area menu and menus within applications. Just get a blank box. If I press somewhere in the box it does the task (e.g. if I press start and press where shut down would be it would shut down) but of course with a blank box I do not know what I am selecting.

Does anyone have any ideas how to fix this without reflashing or is that my only hope? I have tried a restart but still had the same issue.
