combobox

Hi everybody,
A ComboBox within a Form (modal dialog) does not open when clicked, however an item can be selected by using the up/down arrow keys. After clicking on another window and the back on the dialog, the ComboBox works as expected, i.e. expands on click.

Weird... any ideas what could be causing this behavior?

Thanks a lot in advance, Peter
