ComboBox beheavior

Hello all,


When working with a HD Windows 8 tablet, I need to doubletick the screen to select an item in a Combobox. Normal procedure with a mouse works correctly, because with a mouse moving over an item you see the selection of the item and with a click you select the item.

What do I have to do, so I do not have to doubletap the screen? Moving a finger over the ComboBox and releasing it, does select the Item, but is not so easy to do when holding a tablet.

Thanks in advance!

Kind regards,
