VFP 9 support a new extended property lenght.
If you use more than 255 chars in a property, its ok in 9 but this will raise an error in previous versions.
If you use the new _memberdata property, there is good chances that you will break this limit, so backup everything before playing with 9!

There is probably other go-back gotchas to check, but I have already see this one in action :-)

HTH :-)

I can't think of any -- even what the ReportBuilder adds to the FRX contents in various fields shouldn't render the FRX invalid in 7 or 8 -- but there certainly *might* be some.

IMHO, the idea that such extended property descriptions might not be handled properly in previous versions is only common sense, and hardly "crucial" to list in each help topic. It is even a stretch for me to call it a limitation (I had to think hard to think of one <g>).
