David,

Do you have an Error() method that is logging the real error that might be causing VFP to want to kick up some sort of dialog box?

You might also try temporarily building it as an EXE server so the UI error won't mask the problem.

>I had an VFP automation server running which does some INSERT INTO in some heavily used tables.
>The INSERT INTO ... command is sometimes triggering the "User-interface operation not allowed at this time." error 2031.

>I've got SET REPROCESS TO 10
>I'm now trying SET REPROCESS TO 20 and that will probably help

>Any suggestions as to handling on non-attended INSERT handling?

>Does VFP always display a "WAIT WINDOW" style message while attempting to get a header lock with insert? Can it be turned off so I don't get that error?

>Should I modify the error handler to simply keep retrying if the line that caused the error is an "INSERT..." ?
