Ronnie,
typically your LockScreen has been set .t. when this happens. Reset it to .f.
>I created a basic modal form with 3 combo boxes and a list box. When selecting an option in the list box it shells out to IE and all of the objects on the form go blank and I have to 're-click' on each of them to reappear. Ive seen this before but cant remember what property needs to be set to fix it
