Form help in task bar

Hi All,  I'm running IE8 on a Windows7 machine. When I try to view form help in the portal for any form, the form help window goes to the taskbar instead of popping up on screen. The only way I can get it to display full size is to mouse over the task on the task bar, right click on the thumbnail and then click "maximize".  It has to be a browser setting because when I VPN in from  home and access the form from my home computer, it pops up as expected.  Do any of you "gurus" have any idea what setting I need to change to get the form help to display as expected?  Thanks!
