No Beep When Clicking Outside Modal Window of WINDOW.BAS (58102)

SUMMARY

Using a mouse to select outside a modal window created with the WindowOpen procedure of WINDOW.BAS does not produce a beep. This is contrary to Page 575 of the "Microsoft Basic 7.0: Language Reference" manual (for 7.00 and 7.10), which incorrectly says:

When a window is modal, any attempt to select outside the window is unsuccessful and results in a beep.

WINDOW.BAS is a file provided with the User Interface (UI) Toolbox in Microsoft Basic Professional Development System (PDS) Versions 7.00 and 7.10 for MS-DOS.
