Ok, I've only had the opportunity to work with 6.5 for couple days, but I've already hit a block. I still have my 6 installed and it won't open 6.5 files. Am I missing a setting somewhere? I can't find anything in the manuals or the help that tells how to save a 6.5 file to a previous version (i.e. 6).

I know I can export to another format such as OBJ, then import that into 6. But the results aren't always accurate and it seems odd that Maya wouldn't allow you save one version back.
