Im not sure what application you installed and uninstalled but have you gone up too help then to Detect and repair? also update from Help?to see if it can self repair itself.
I've microsoft word 2002(10.3416.3501) SP-1 on a Windows XP Professional Version 2002. I installed a particular software and then the Word menu started behaving abruptly. Now the main menu items on the menu bar (like File, Edit, View etc.) are visible but their corresponding submenu is not visible anymore. What is visible is only the outline of the dropdown menu container. On uninstalling the software that's working fine but its also working fine on another machine with same configuration but lots of additional software loaded. Any idea what could be wrong?
