>>I can not the Value_assign method to work with a checkbox control. When I click on the checkbox the value of the checkbox toggles true and false visually, but the value_assign does not fire. I have put a breakpoint in there, no dice, not even SET STEP ON works. Any ideas why it isn't working? Can anyone reproduce this behaviour with VFP6 SP4?

But it is getting set. The VFP help isn't clear on whether assign only fires if the property is programatically set.
