Video won't show COMBOBOX in action

[Chinner]

I am trying to stream/record the operation of an MS Form - under excel and VBA - featuring numerous combo boxes in action. All I get is a series of still life videos showing the results of a combo box selection, not the actual selection action itself. I've increased the fps to 60 but still no help.

Any help would be appreciated. [I used the Auto Configuration Wizard to do the initial setup.]
