Suddenly (since yesterday) I can not open a new window from the task bar unless I close or minimize the window I am currently in. For instance, if I am in Photoshop or on a web page I can not open Outlook unless I minimize or close the program I am in. Same thing if I'm composing an email, I can't go to outlook or open any other program unless I minimize what I am working on. This occurs also in IE or FF. The programs are on the task bar and are lit up. I believe they are actually open but aren't "coming to the front".
Hope my non tech explanation is clear. This is very frustrating and time consuming to deal with.
