An excellent time to remind developers to use the IN clause instead of making any assumptions on the currently selected work area. > Unfortunately, I haven't been able to reproduce this error in > my test environments so I thought that I could add a delete trigger that > would fire off and do 2 things: one would be to capture the current > system state at that point in time including call stack, program/method, > etc and log it for me and two would be to return false on the trigger > and automatically recall/revert the deletion.

I think your idea is fine, but since it's happening now and you're unaware of it, perhaps just the email to you with that good info you're capturing will set the wheels in motion to fix it. You will have a couple more episodes of rogue deletes perhaps, but at least you'll be made aware instantly via email and can get to the heart of the matter faster.
