Here’s my first impression on flick panning, a new feature added to CS4.  When you click, drag, and release, the image glides and slides all over the place.  ME NO LIKEY OKAY!?

I found the answer already, after I recorded the screencast, of course. It’s so easy – just go to: Edit->Preferences->General and then uncheck “Enable Flick Panning”

A great video tutorial by Deke McClelland on how to use the reset and purge functions in Photoshop CS4 to increase the performance.  Clean out Photoshop’s plumbing when things get clogged up: Reset and purge.
