Resolution problem with Cubase 7

Hi everyone
I’ve just installed a new Windows 8 and Cubase 5, and Cubase 7 on my new computer
I’m using a plasma TV as a PC screen, had a small problem before, but with C7 on my W8 it’s too much
I can’t even approach the export button on the export menu.
Is there anyway to adjust C7 size to fit my screen better?
