At times the PowerDirector 11 interface fails to paint some buttons, icons, etc. until the area where they should appear is moused over.

Nearly the entire EDIT interface may be devoid of buttons. This occurred recently when toggling from the CREATE (DVD) menu back to the EDIT menu. Most left-side and top icons were gone.

On other occasions, as PD is launched, a select few icons - OPTIONS, UNDO, REDO for example - may not be drawn.

Not likely due to system deficiencies. Settings? Ideas welcomed.
