>The VFP doc says that one cannot SETFOCUS in a VALID, RANGE-HIGH/LOW, etc. And yet, I have a form where I accidentally did this and Lo! it works most of the time, but fires an error "cannot setfocus in valid, ..." some of the time. I actually stepped through the code in VALID and watched it pass right over the SETFOCUS.

Could it be that Event Reading is not on at the moment the message does NOT appear ? -> at that moment you can do anthing and events (nor checks upon things) won't fire. And of course a Valid can be called explicitly...
Note that when Event Reading is off, some Event (triggers) will get buffered until it's On (Read Events), and you won't be able to find the logic in things happening.
