Thanks for the input Remus.
An update - I uninstalled SU7 and that solved some of the weird problems I was having between SU and Hypershot (images opening in HyperShot that looked like something from a bad move about LSD). So I'm back to work but I still have the strange file saving issue.
I've attached a screenshot of the folder hierarchy but I've never done that before so I don't know if it will show up correctly on the forum.
This shot is after working with a drawing called SpiralSU6Classic. All of the numbered files 0 through 9 are the automatic saves during my most recent period of working on the drawing. And two other things to notice - there's 2 files called SpiralSU6Classic and there are no backup files.
Doubt I'll ever solve this one but thought I'd send off an update anyways.
Thanks again
