Getting white surround on PS document

#1
Hi Everyone,

I was using the paint bucket at the time and somehow managed to color the surround area of the PS document. This white surround is coming up on all my documents now and I cannot seem to get rid of it, I've tried changing the workspace but that doesn't do anything. I've attached a screen shot of the problem. Any ideas on how to get rid of this surround ? Thanks :neutral:
