Record already locked by this session

Hi :)

I've posted a question a while ago about an error I was getting.  The error is "record already locked by this session" and occurs when I try to put a TTable in edit mode.  Here is a link to the previous question:  https://www.experts-exchange.com/questions/21071319/Record-already-locked-by-this-session.html


People told me that the problem probably occured because of locked blocks within the dataset.  I quickly solved the problem by doing a close/open after each post.  This worked ok for a while but now I can't use this solution due to the fact that it is too slow for my application.

So here is my question again:  how can I get rid of the error "record already locked by this session".

Thanks :)
