Has anyone looked at the locking behavior of _Access and _Assign methods? I know for example that the _Assign method will not fire if it changes its own property. I suspect that the property being managed by the _Access or _Assign method cannot be changed while the code is running. Does anyone know if other property values can be changed from outside the object while one property's _Access or _Assign code is running?
The basic question is how many semaphores does VFP use to control access to object properties (one per object instance, one per class, one per property)?

TIA
