Not full screen
 

My pages are not covering the full screen and I cannot access the "maximise" button. Only the "minimise" 0ne is visible and I Whilst I can move page up I cannot move it any further left. Any help would be appreciated.

Try grabbing the end of the screen and drag it over, do this for the top, bottom, and both sides. Once you get it full screen then hit the Maximize button, then close and reopen, should be normal.

You can try pressing F11 also,that should make it go full screen..... (@ least on all IE versions it does)

Good luck buddy :)
