I've discovered some bizarre behaviour if a report is run with the PREVIEW option in the regular Report Preview Window. If the window is maximized and then closed with the window close icon (rather than the Close Preview option on the Report Preview task bar) the system menu will fail to respond to mouse clicks (ie. options may be selected and highlighted but nothing happens when clicked).

Is there anyway to prevent this behaviour other than running the report in a user defined window (which won't have scolling capablity !)
