Why doesn't window management software like Divvy work with Adobe Photoshop? I use both Divvy and SizeUp to manage my  windows. They work fine with application windows with the exceptions of Adobe Photoshop. They just don't seem to work with Photoshop. Whenever I apply them on Photoshop the window just acts bizarrely.

How may I address this?
turns out that slate works just fine with photoshop.. it's a bit more technical/harder to set up than the other two.. but based on the people i've spoken with.. it's well worth the trouble
