Hi Will try that. to explain better there is actually a list of components, one of which is a country selector. Changing the country changes the entire display (displayed components and positions etc). The easiest way to refresh the display is to clear all components and re initialise. I assume the message I post wouldn't be received until the event has finished firing ? (will make the postmessage the last step). Thanks Conor and Jeremy Rob Conor Boyd wrote: The way you've described it "smells" a bit to me. Why do you need to free the combobox? Why not just hide it or something similar?However, if you truly want to do it, look into posting a message to the form using PostMessage, and then handle the message on the form, and free the combobox at that point.

As part of that refresh the combobox is freed. This causes an AV as the combo box has not yet finished processing its event but is being freed. What would be the best way of dealing with this scenario?
