Records lock on copying to blob field

[jlockley]

Actually on clicking Blob field. All records lock, so that files cannot be pasted or inserted. This did not happen previously.
This is Paradox 10 in XP. Thre are no methods or events attached. IT is a stand single database.
When I have experienced this behavior in the past, I have found that closing and reopening the table stops records from locking. This time it does not.

Any thoughts?

Thanks.

Adding a note here: Restarting Windows did resolve the problem, so the question is entirely academic at this point. Still, it would be interesting to know what causes the occasional behavior.
