I have a form with a number of controls such as combo boxes and labels on it. When I select an item from a combo box that will update other controls on the form it seems to lose focus on a number of controls and just leaves a white space where they should be. If I click on them the controls will appear but still miss their borders. I've tried refreshing the controls, re-setting focus and doevents (although i've not used this before) without success. However if I step though my code i have no problem and can see all controls. Any thoughts would be greatly appreciated.
