I'm trying to get Photoshop CS3 to run in Linux Mint.

So far it's installed, but when I run it I get a blank license agreement window with "Cancel," "Decline," and "Accept" buttons on it that don't work. It can't be closed and basically makes every other button non-functional (I have to end it through System Monitor or by terminal). I can see the regular Photoshop window behind it, though, so I'm thinking that if I just find a way to get past this I'll be all set.

Does anyone know what the problem is? Is it obvious and I'm stupid, or is it basically impossible to fix?
