where did my browser go?

Help! I pushed some button -- I think it was a function button (PC, not MAC) and the frame around the webpage disappeared. The browser (or maybe it's the task bar?) shows up if I move the cursor to the top of the page, but I want it back the way it was

thanks in advance...

oh, okay. I figured it out, jumped the gun in asking for help. Sorry! just had to click "exit full screen" DUH.

Mods, please delete thread...or send it away, or whatever it is you do with threads such as these...

Thanks!
