Alan,
It's a known bug up till VFP7. There are multiple workarounds :

Add a property to form called lHangingValidation. Suppose your valid routine does a checking and returns llValid

*...
return llValid

Change it to :
*...
thisform.lhangingvalidation = !llValid
return llValid

*Grid.Valid
return !thisform.lHangingValidation

Is one way.

For a better handling check FoxyClasses that does it at grid class level.
