I'm using Adobe Photoshop Elements 5.0.2 with Windows Vista. Often, when I'm editing my drawings, the program will lock up on me. When I move the mouse pointer over the drop-down menus at the top, they flicker oddly, and I can't select any commands. I can't close my open files, or save what I've done from my latest command. When I try to close anything, I get the Windows "error" tone.

The only thing to do at this point is open Task Manager, and tell it to end Photoshop. I have to do this a couple of times to get it to close Photoshop, and I get the pop-up window stating "This program is not responding"

Has anyone else had this problem with Photoshop, and is there an upgrade or patch for it? Failing that, how about a big hammer?
