Does it work when you save an animated gif? And what about individual frames?
No, it does not work at all neither for animated gifs nor for individual frames. I can't save anything.
That's strange... Are you running out of disk space, perhaps? Or are you on a computer with restricted privileges? (e.g. a school computer?)
Ok, now I found the problem! It was my antivirus that blocked the saving process. I'm sorry if I thought this was a bug of your software.
It's okay, glad you solved it!
