Hi Sorken,

I have never experienced this problem either. However without identifying the exact specifics of what your OS, Illustrator versions used, machine specs, drive space etc. it's just a little sketchy to make an intelligent assist on the matter. If you can be more specific about it all, we can probably figure it out because it's not a normal thing. I think the other poster's query about the files that trigger it and settings used in saving are on a great track. So, what settings and what exactly is the file size, type, and composition. Like save it as what ai, eps, pdf...
