Ps3 Chat box Problem

I've accidentally elongated my chat box (not full screened) & I can't seem to shrink it to it's normal size, & it's VERY distracting. Does anyone have any advice on how to reset it?

I have already tried logging out & back in again, but it did nothing.
& I have also gone into the chat settings & restored to default.

Please help T.T

Try pressing L1 and R3 to get mouse pointer up and grab the corner of the chat box with L2. Should be able to adjust it this way.

Omg thank you soooo much. It was really bugging me. You're my hero ;) xD
