I'm having problems with drop down menus in various programmes. Currently trying to reinstall some software and there is a drop down menu to select which hardware I'm using but the drop down menu just flashes when I click on it then disappears. I also have intermittent problems in MS Office 2003 applications. For example, in Excel, I can't right click and then select from the menu as the menu again just flashes for a micro second. I have to use alternative methods of copying and pasting and so on.
This started at some point recently but I cannot pinpoint it as I have recently had to reinstall everything after a HDD failure. All was OK for a while (I think).
