Last night in Photoshop, all of the menus, lettering, etc. started to get weird and leave out letters (I think it was mainly "i" and "l". I stopped the program and restarted and everything was fine. Then, later on, for no reason, the Photoshop Icon disappeared from the dock of my macbook. I clicked and dragged from the Applications menu, to return it to the dock, but now when I try to open Photoshop (whether from the dock or the applications menu) Photoshop usually will not open or takes a VERY LONG TIME to open (Force Quit Box says Photoshop is not responding). The rare time I get Photoshop open, it will no longer recognize any of the .png files that it has been recognizing. I'm using CS3, and I know it's an older version, but this still seems unreasonable...also, when I try to open Photoshop now, my computer opens up Firefox and a prompt to download Adobe Flash (even though I already have a more recent download of Flash). Any help is appreciated...I'm a novice though...if you get too technical I'll get lost! Thanks!
