I have PS CS4, love it. but it has a quirk I've noticed now on three systems already.

Every once in a random while, when you are trying to select/color/move something, photoshop seems to lose where your mouse pointer is and instead will put whatever your doing on a random part of the screen.

So say you want to move an object, you click, and drag. Well at times as I go to drag, the object I'm moving vanish and appear fare below where my curser is. Others it will zip so fare off the canvas I can't find it and have to undo to bring it back. This is instant, not like you can see it moving away from the mouse.


This is random, 100% random and will do it with anything you click and drag. Trying to color something? click and make a strike? The stroke will appear elsewhere rather then where your pointer is. Making a selection? again will show up elsewhere. The location of whatever your dragging also seems to move randomly.

I've seen this only in CS4, not CS2 (I went right from 2 to 4)and is making coloring and doing stuff rather frustrating. I can go days, weeks with out it popping up, like with something I've been working on, I've almost forgotten about this, and now JUST now it's started back up again.

So does anyone else have this weird quirk?
