yes to both < s>... the object stays in memory but you cannot access it using the original memvar and you probably found a bug in MM.

regarding the first part, while you cannot access the object using the original (now released) memvar, the other thing(s) that hold references to the 'dead' (but not really) object will still work! For what it's worth, in such a case I can see why DESTROY() would not run.
But I am still of the opinion that this is a BAD 'feature' of VFP. When I say RELEASE it should RELEASE the object reference AND the object and let me get a later error when I try to reference the now deceased objct again.

>>As JayeshP says, *IF* your code puts **ANY** reference to an object's property, or even stores an object reference patial 'path' (for example: xxx = oObject.Treeview) then RELEASE will do nothing to the actual object! Yes, it will release the memvar you specify but it will NOT release the object.
