I currently have a mainform/Subform w/tabs(pages)- note all tabs data source is the same underlying table. The Subform does contain other subforms where this flickering does not occur. There is a refresh on the main form but not on the subform. However, when moving the mouse/cursor over the subform the screen and the objects flicker. What can be causing this issue - it does not prevent data entry, however, the user finds it very annoying.
