Every time I install photoshop on my new computer it gets progressively worse with the glitches. The zoom will get stuck it will show the % on the layer going higher and lower however the document doesn't change. The marquee tool when I make a square / rectangle it will flash (or blink) and when I move it goes back in forth from the place I moved it from to the place I moved it to. And a few other annoying glitches, like when I open a file into photoshop the screen is just black.
I have tried uninstalling then cleaning registry and then using the adobe cleanup tool then reinstalling, no luck (I have done this a few times with the older versions I have to, this issue happens on ever version I have of photoshop (CS5, CS5.5 & CS6) and only on this new computer, my old computer with crappy specs never had these problems)
I would appreciate any help!
