vfp 3.0 in win 95

I have browse screens with combo boxes
that on double click automatically pulls
record into a pageframe form. When pageframe
closes, RETURN is issued to go back to browse
screen so that database files can close.

Things work great until the magic 3rd record which
for some reason is leaving the database or table
wide open, thought I had this licked but it's back
to haunt me again.....

These are free tables, they are set EXCLUSIVE ON, and
I issue CLOSE DATABASE AND CLOSE TABLE COMMANDS to assure
that they close. Why are they remaining open after that
magic 3rd record? The only work around is to close the
entire program and restart it.

User is getting VERY FRUSTRATED! Any thoughts????
Sorry for the shouting, it's been a long day....
