CorelDRAW Graphics Suite X6 :: Files Are Saving In Huge Sizes?

Several days ago I noticed my files sizes were enormous. I was unable to even open them to work on them. Something that was once 517KB becomes 161MB the next time I save it.

After I installed the Corel update this morning, things were back to working as usual. But tonight it's back to the huge files. I saved a simple greeting card file - no halftones, no gradients, etc. It saved at 19.7MB. A few minutes later after making some small changes - saving again it was now 118 MB.

I tried saving to a lower version of Corel and ver 15 it was the same scenario. When saving to 12, 13, & 14 the files were normal, small sizes. But after a few hours even those versions were saving at huge sizes.

I've had a friend check her computer using the same file - she has the exact same computer & on Corel X6. All of her files are nice and small like they are supposed to be.

I've run virus checks and nothing is coming up. I am on Windows 7 64 bit.

Other than recreating all of my files every time I use them - I have no way of saving usable .cdr files.
