AutoCAD Architecture :: Scalelistedit Affecting AEC Content

I have 2 files, A100 and C100, with C100 being xrefed into A100.  Both have a few other xrefs in them, being used for whatever reasons, and must stay.If you open either file without the other being present, they open fine, but if they can find each other there's a 20-40 minute lockup.

C100 being a civil drawing, I thought the problem was one of the missing .shx files.  So after spending countless hours trying to track it down, I finally noticed a warning when trying to open the files together that C100 had 2200+ scale lists. Using 2008 in the office, scalelistedit gives a runtime error, as well as the 2008 install at home.  Using 2010, scalelistedit is successful in solving my 20-40 minute problem. (I did save back down to 2007..)

Now, back in 2008, the Style Manager won't open, as it says there is content from a newer version in the file.  Also, any xrefs with AEC content, walls etc, come in without displaying said content.
