I'm not really sure this is a hardware problem or a hardware configuration problem or neither. When I have a couple windows open and they are listed in my taskbar and I want to go from one to another. Once the mouse leaves the taskbar area the window closes. If I click on it twice in the taskbar it stays open provided I don't leave the confines of that window. Does this sound like a configuration poblem? Has anyone encountered this problem and how did you resolve it? Thanks in advance for any advice.
