Don't know whether this is related to your problem, but reading what you wrote gave me a strong deja vu, and I've dug out message #741284 - but now I'm not certain you got the same problem.

The control flipping back to its controlsource value usually happens when a refresh occurs before the validation ends. Set a break in combo.refresh and track the value before and after - if you're refreshing while in interactive change, this may be it. The cure is to have no parent-level refreshing here, but only control level. So in listbox.interactivechange try to do no refreshes, or try to replace the value into the combo's controlsource (instead of going for its .value). Basically, a refresh re-reads the controlsource of each control and copies its value into .value - and you've just changed the value.

Now why does it work when debugger is on? I think in that case your control has lost the focus, and something that triggers a refresh is not happening.

You see I'm in a dark here, no exact science. I'm guessing based on some things that happened to me before, but who knows - some of it may apply to your case.
