Summary:

PROBLEM ID: PM9012013

SYMPTOMS

If the Group Main and Control Panel windows are arranged according to the diagram listed below and the Group Main window has been set to “Cursor Blink”, when the Group Main window is moved or sized, a part of the system menu will remain painted on the Control Panel while the move or size is in progress. This problem also occurs with the “Time” and “Date” fields of the Control Panel.

By covering these fields and then switching into the window tracking of another window, it is possible to have a rectangular region be temporarily improperly painted.
