Edit control/combobox warning
    =============================

    Note: This does not apply to edit/combobox controls in dialogs.

    If you encounter general protection faults (Windows errors) when
    using edit controls and/or comboboxes, this indicates that you
    should increase your application's heap size.  This can be done
    very easily by including the following line in the .DEF file that
    you use when linking the application:

            heapsize    5120

    Note: that's heapsize, not stacksize.

    This parameter determines the maximum size of the edit control.  The
    5120 is just an example, you may be happy with less or need more.
