I'm not sure whether I should be asking this kind of question here, but...
When I'm working in Photoshop (CS5 currently, have had it with previous versions as well), when I've zoomed in on the file and have the hand tool selected, Photoshop sometimes zooms out as I drag with the hand tool. It zooms to 'fit screen' size, and zooms back in when i release the mouse button. It does so at random times, and at those times I'm not pressing any buttons other than the left mouse button.
It's really driving me nuts, does any of you know if this is fixable?
