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?
Answer
You are experiencing a Bird’s-Eye View feature’s bug:
Here’s a way to reproduce this glitch: while zoomed, hold down ANY tool shortcut you’re not currently using (i.e. hold B while you have Clone Stamp selected) and, at the same time, try to use the spacebar pan.
It still isn’t fixed in Photoshop 13.0.1 (which ships with CS6) and the only way to get rid of this bug at the moment is to disable OpenGL features*: Preferences => Performance... => Graphics Processor Settings block => uncheck Use Graphics Processor checkbox and restart Photoshop.
* I would highly suggest not doing so though, as it will disable many neat features and optimisations.
