Have you updated Photoshop to either version 12.0.4 or 12.0.1?
No one should be using version "12".
Are you on Macintosh or Windows? What exact version of the OS?
Were you maybe using an external monitor that you disconnected?
Have you tried deleting your Photoshop preferences? Hold down Commad+Option+Shift on the Mac as you launch Photoshop; if on Windows, it's Control+Alt+Shift.

Hello Station two,
Thanks for the reply and shall do all the updates etc and await the outcome.
Well, have done all the updates and is still doing this.How do I contact adobe direct to complain!
You have not supplied any of the information requested in my post #1 nor have you read the link supplied there.
Complaining won't help you any.
...but you're welcome to get on the phone to Adobe tech support and spend a few hours attempting to get through to the folks in India, if you can understand their accent.
oh excuse me for not complying with the rules obersturmfuehrer station 2. And I did have a read and how would you know if I didn't? To answer your question I am using mac 10. 5.
