Another OS X Lion Weirdness

[Peter Haworth]

I just opened a document in the iWork/Numbers spreadsheet program that I
hadn't opened for perhaps a couple of weeks.  It opened just fine but when
I tried to make a change to it I got the message:

The file "Costs" is locked because you haven't made any changes to it
recently.

There were options to Unlock, Work on a duplicate copy or Cancel the change.

So now Apple apparently thinks it's appropriate to silently lock files
behind my back on the basis of me not accessing them for some arbitrary,
unknown period of time.

Does anyone know of a way to switch off this"feature"?
