I've been having this problem for at least a month now, and it's getting really annoying. Basically, while I'm using a program, the File/Edit/View/Tools/etc. menu will randomly open. I'm not accidentally pressing any buttons or anything, it just happens. While I'm typing on here (Firefox), before I know it I'll be pressing enter on one of those menus and crazy stuff will be happening. While I'm in Paint or CS3 using a toolbrush or something, it will cut off my paint supply and up top a menu will be open. It even happens in iTunes, WMP, OpenOffice, and Vuze (maybe more, but I can remember instances with those programs). Also, sometimes while I'm typing it will give me a ding and cut off my ability to type until I click the field. This whole thing seems to come and go. For example, right now one of those things I told about are happening at least once every 30 sec. But other times, it seems I can go a day with no problems. I've scanned with MSE and MWB but neither find anything bad. So, I'm up to any suggestions and hopefully you guys can help me out.
