I've created layer frames for my homework - GIF animation - and cannot save the file as animation. It shows empty dialog window with only three buttons to operate: Help, Export and Cancel.

I'm using GIMP 2.8.2
P.S. - I've posted already one topic with this problem and have received information the bug is repaired in latest version. Latest version is the 2.8.2 and the bug still appears... Looks like there's something wrong in some plug-in libraries... If exists any repair for export-gif.exe (or something like that) let's link me at. If not...
