XP Pro. When more than one program is running and I try to switch between them by clicking on the program on the taskbar, it will not respond (It will not bring that window in front). The taskbar flashes orange. If I click it three times it will finally respond. Not sure why this is happening and I have not been able to figure it out using "tech support" or troubleshooting. One other person on this forum had the same problem and said the problem was with his D Link wireless card configuration utility. I don't even know what that is but I'm pretty sure I don't have one. Any help would be greatly appreciated but please don't get too technical in your response.
