SUMMARY
When a multiline edit control is created that is less than one system character in height, the text in the edit control will not be displayed and subsequent attempts to enter text will cause the edit control to beep. This functionality is an invalid multiline edit control under Microsoft Windows versions 3.0 and later, even though this construct does work in Windows versions 2.x.

The multiline edit control also checks to see if the next line of text is displayable. If the next line of text is not displayable, it will beep to let you know that you have reached the limit of the edit control.

There is a similar situation with a control that overlaps another control in a dialog box. This construct is also considered invalid; thus, the second control will not be displayed.
