I have been running sl fine all morning. (phoenix) Went to derender prims using ALT+CTRL+SHFT+9 but may have hit a wrong key. I now have a black border around my screen, graphics are large and oldschool. I just want to be able to get back to normal. Any help please. BTW I can run any other program and it is fine, log into sl it changes the whole pc setting, log off sl and it reverts back to normal.
