stackfileversion and locking 6.5.2

[Geoff Canyon]

I have a stack that I moved to 7.0.2 for a few days without thinking, and I
want to move it back. I tried this in the message box:


set the stackfileversion to 5.5;lock messages;save stack
"versionProblem";close stack "versionProblem"


and after that if I open it in 6.5.2 or 6.7, they lock up with the spinning
beach ball of death. I don't think I put anything into the stack that
requires 7, and LC dies even if I lock messages before opening the stack.


Any ideas?
