Im at work and would appreciate any help guys. Im working on a G3 Mac running OS9.1 and photoshop 5.0, and for a while now its just gone mad, the only colours in its pallette are yellow, blue and black!!! So if I open up any image all I get it as is a combination of these colours. Im pretty sure it's not the computer itself with the problem (not entirely sure though) as if I open up another program, say freehand, the colours are absolutely fine in that software - its only photoshop with the problem. I've tried everything I can think of, i.e color preferences, changing image type, palette type etc but with no luck at all. Any ideas? like I said and help much appreicated.
