Thanks Allen, I thought you may have had the answer as I do have a clock function running all the time, but I have a delay in that loop. I figured out what is going wrong. If I maximize the .vi, then the task bar will not function when the .vi is running. So, I did not maximize the .vi, and chose 'Size the front panel to the width and height of the entire screen' on the Window Size category under vi properties, and the task bar now works when the .vi is running. I feel that I should be able to have the front panel maximized, and still use the task bar. I do have 'Always on top' selected in my Start/Settings/Taskbar options. Thanks!
