Maybe I don't understand the problem.

You have a checkbox. When the user clicks the checkbox you want to execute a piece of code but you don't want the value of the checkbox to change.

I tried this

*Checkbox.When
this.click()
return .F.

*Checkbox.Click
messagebox("Checkbox Clicked")

alternatively
*Checkbox when
messagebox("Checkbox Clicked")
return .F.

both displayed the messagebox without changing the value of the checkbox.
