Why does that do that

Hi, could someone help me? This happened twice now. Ok i was sending a PM and i put in a smilie but i clicked on it to move the smile up a bit and it went forward a page so i then clicked back and my PM i was about to send it but it had disappeared again :eek: :mad:

I guess you just have to make sure that that doesn't happen again ;) Just click on the right thing..lol

no really..no idea how to change that. May be a cashing option...
