Disappearing Instruments when Auto-Numbering

[bjw]

So I've got a weird problem I've never experienced before. I'm using drafting of a theatre I've designed in before, but this is the first time in 2010. I can place instruments and assign information to them, but every time I manually set the positions to Auto Number, the instruments on that pipe disappear. Has anyone encountered this problem? Any thoughts?

I see no one has had this problem before...but I have a new twist on it:

The instruments aren't actually disappearing, there just seems to be a bug in the program where they simply don't appear. I can renumber my positions, then if I turn the visibility of my "instruments" class off then on again they reappear, all good. It's very weird, and I wish it wouldn't happen, but at least there's a way around it.

Any chance this is a compatibility issue between an old, many times updated file? It was originally created in 12.5, then upgraded to '08, '09, and finally '10.

Did they begin life in a previous version of VW

And did the instrument symbols, label legends, and record formats come from an earlier version...

This is a little late in coming, because I eventually found a way around the problem. The answer to both of the previous questions is "yes". The file was originally created in VW12.5 and the symbols came from a previous version of VW. I'm not sure about the record formats, though that's probably the likely answer. The solution was to use the standard symbols included with VW2010.

thanks guys
