Since the Gimp 2.8 update came out, I'm been having some problems with it.

The "Export Image as GIF" pop-up is broken, and just shows three buttons GTK-style:

I just re-installed the app today, but it's still happening.
I also have Gimp (same version) installed on the C drive (not Liberkey) and it works the way it's supposed to.

There don't seem to be any options within the app to fix this so I'm wondering if there's something wrong with the way Liberkey installed it?

(using Windows 7 Ultimate, 64-bit)


Edit: the same (bugged) pop-up displays when exporting to PNG as well, but when exporting to JPG it has the options showing.
