Tore

Thank you for advicing
The problem is that I sell low price software to a large number of people instead of higher prices software
to large companies (less units)

So it's not possible to give personal attention for them

Maybe that is why I have a large rate of corruption data cases
I solved many of corruption problems automatically by detecting bad tables and asking the
user to contact me, or giving him the option of restoring form backup

It the past, user was not aware he had a bad file until serious problem happened

With your help and many valuable members of this forum, I was able to develop
many solutions to automate my softwares

I will advise in the software documentation about abnormal termination problems
