I have a funky issue that I've come across. I have several files that were made using Illustrator CS3. There is a particular type of path item in them (a basic shape path with gaussian blur applied to them) that when I open up the file using CS6 that path item is treated by Illustrator like it's a embedded image.
I've remade those items as an actual path item with gaussian blur applied, and all seems fine until I save and re-open the file, they become embedded images again. I'm thinking it might be an issue with a setting somewhere but I'm not finding it.
I have several files of the same type that don't have this issue but I'm not finding any difference between them. At this point I'm stumped...any suggestions?
