Hi Akshat.. I attached a picture of the error message in my last post.

Another thing is that when this happens after I click on a button that causes it, looks like the program is doing something for a second before the error message appears.  The little windows circle appears for that second.  Also it forces a null .dbf to appear in the directory.  Named this or similar:  _QSQL518.DBF.
