'Unable to Open' error in NT

When I using the de{*word*81}, and abend a delphi exe in which I've opened
a table, the next time I run the exe and try to open the table I get
an 'Unable to open' error.  The I have to log out of my NT session in
order to clear the error.  Needless to say, this is a major pain in
the ass.

Has anyone else resolved this problem?
