I have a problem with the pointing device or any external mouse connected to my Toshiba Satellite A300 - 15M. I use windows vista. When I just move the cursor above any icon, it selects it as if I clicked on it! and if I clicked the icon once, it opens as if I double clicked it! Also when the icon is selected, it's name becomes underlined... I thought it's related to the mouse setting, I looked for it but I didn't find anything to change...
