[AccessD] A2007 Properties during runtime

Does anyone know how to enable properties during runtime?

If was trying to troubleshoot a cascading combobox rowsource to see if
it is reading correctly.

I know I can check if many different ways, but I like to enable
properties and look at the data tab's rowsource field as I am clicking
on things.

It seems I can't display the combo box properties in runtime.

Does anybody know how?
