Commented Issue: Crashed while editing a GIF [29]

I want to report that it crashed on my windows 8.1 !!!
It's the first time it crashed after using it several times without any crash or problem!!
I got to admit that my system is currently being at a bad state in general... even though this crash information might help you (the developer) make this software better....
