I have a brand new Toshiba laptop Computer with pre-installed Vista. In using it, I've found this glitch and don't know if I can explain it correctly but I'll try. When I click on a file on the desktop, on a item to view in this forum, on a box in excel, on an item in the task bar, or on a game piece in majong... the START MENU will pop up. I then have to move the mouse over just a bit and re-click and the correct feature will work correctly. I'm not sure how to explain it to a "windows troubleshooter" so I was searching the web when i found this site. I actually like Vista and most..... most of it's applications. This problem gets frustrating at times when I'm trying to complete a task and am going at a steady pace and then this glitch happens. It only happens on mouse clicks (touchpad is the only mouse I have used on my computer). Any input, suggestions would be appreciated.
