>What about this... would anything go haywire because we use the beforeopentables event to open tables? Maybe foxpro internally isn't expecting tables to open before their opentables event?

(sorry John, that first post was really meant for Shawn)

I'm not sure either - but it's probably worth testing without that somewhat unusual order of actions, just to rule it out, at least.

BTW, I solved (mostly, anyway) my ISO problem yesterday by doing the following: I copied my entire DB directory to new place, and ZAPped all the tables and removed all the indexes, then validated the DBCs. Since my app will not run without a little data, I created a few fresh test records with new indexes, just enough to get the app to function. The result? No more errors, clean as a whistle. Today I'm going to build the DB up larger, and continue testing. But at least I know the problem is data-related now, major progress.

I would advise you do the same at this point, if you haven't yet. It was a real breakthrough for a very thorny bug.
