Camera Raw opening in wrong monitor

[Colcam]

About a week ago, the camera raw window started appearing in the secondary monitor of my pair and I cannot stop it from starting there. It appears with the title bar up off the top of the screen and I can just barely grab the top corner of it from the edge of the primary monitor and drag it out where I can move it.
Prior to this, if I opened a raw file directly into CS3, it would start in the primary where CS3 is placed or if I right clicked a raw file in Bridge and chose open in CR, then it would open in the secondary monitor where Bridge is located. Now I don't get the choice. This was happening before the latest updates which all appear okay. System is a PC by the way.
It matters not where I close the CR screen, it still appears on the secondary monitor!

I would appreciate any assistance.

Maybe try switching it to a single screen setup (save a settings profile of the one you are on first), or using a higher res to see if you can access the top bit. I vaguely remember having this problem, but can't remember how I resolved it.

Okay, here's a lesson for us all. I had accidentally hit the F key (Full screen mode toggle) whilst in there and it fills the screen with no hope of getting to the edges. Once back in normal mode all is well again!!!!!
Thanks for the help
