This can occur when you are using a 64-bit version of Internet Explorer (IE). You must use the 32-bit version of this browser.
Any 64-bit version of Windows using IE7 and IE8 may have two versions of Internet Explorer. To determine if this is the case, click the Windows Start button and point to All Programs. If you see two listings for Internet Explorer, one with 64-bit beside it, could you ensure you are only using the other program version for Gannon Online?
Using IE8 with Gannon Online, you should also use compatibility mode. To turn this mode on, click the button that looks like a broken sheet of paper to the right of the address bar in Internet Explorer and the left of the Refresh button.
Also, I suggest using other supported browsers, such as Google Chrome or Microsoft Edge.
