You can put some code in the form's .deactivate method, something like this:

if not isnull(this.activecontrol)
   this.lValidated=this.activecontrol.valid()
   if not this.lvalidated
      this.lastActiveControl=this.activecontrol
   else
      this.lastActiveControl=null
   endif
else
   this.lvalidated=.t.
   this.lastActiveControl=null
endif

Then in the .activate

if not isnull(this.lastactivecontrol)
   this.lastactivecontrol.setfocus
endif

Of course, this would need a little more checking, making sure the lastactivecontrol is null initially. You may also have problems if form.deactivate happens during a valid() (could create a loop if you don't check for that), or some other problems (messagebox(), popping up any child form), but these can be worked around.
