graphics lag at startup

[.paul.]

when my form loads, it doesn't instantly display properly.
i've tried doevents + refresh but both comboboxes on my form take a few seconds to display properly.
i've got a backgroundworker that i call in the form_load event, that loads 12000+ items into a listview but that shouldn't slow the loading down?

Provide the code behind this form and background worker and we'll be able to assist better.
