>It's the same message as if you tried USEing a table without the CDX and SET SAFETY is ON, "Structural CDX file is not found". But with SET SAFETY OFF you don't get the above message if ON ERROR is VFP's default. However if you use ON ERROR DO SOMETHING the ON ERROR is triggered even with SET SAFETY OFF.

There is a bug that has existed since the Fox2.x days. This sounds like the same one. Under Fox2.x, my scheme to rebuild tables was to DELETE the CDX, then INDEX ON . This causes the same error to trigger when I open the table. If I tried this in the command window without an error handler, I got the error, hit ignore, then INDEXed. However while using my error handler, I had to take a different approach: USE the table, error handler fires, ignore the error, USE the table again. In other words, I had to use the table twice. It's a strange one, but that's how I got around it. And as far as I'm concerned, it is a bug.
