cannot exit full screen on a particular page

I am using Windows 7 and IE8.

I have two user name accounts set up on my laptop. When I click on this one particular link--inside the company website that I work for--the page opens full screen when I am logged on under one user name but not on the other user name. I have tried hitting Esc, F11, etc. and nothing will let me exit fullscreen. I can hit Alt + space bar or Alt + F4 and get a menu but size is grayed out. I can use the menu to minimize to get out of the application but under this one particular user name I can't get the address bar or the - [] + toolbar to show. I have noticed that at the end of the address--under the user name that I can see the address bar--the address ends with a BHO ending.

Would the reason this one page acts this way is somehow the page is stored in something like temp files or history somewhere?

Would anyone know of any tips or tricks that I can use to make a change so this page will not load fullscreen?

Thanks in advance for any help,
