Multiple Monitors - Program Expands To Next Monitor

[Merlin2000]

It seems like a few programs, such as Adobe Photoshop CS4 and Adobe Dreamweaver CS4 (seems to be limited to Adobe), expand past my main monitor, and reach the monitors to the left and right.

This happens when the programs are maximized.

I've included two screenshots of this issue. Notice the additional black border around the main screen (middle one).
