Revision History
-------- -------

4-Oct-04 D. Cook
	Modified the OnDraw code to display app icon instead of the ellipse
	the app wizard provides. Revised the IDI_ABOUTDLL icon.

9-Oct-04 D. Cook
	Added workaround to fix the problem with VB when OLEMISC_INVISIBLEATRUNTIME
	is set. VB will not create a window when this attribute is set, therefore
	the m_hWnd is NULL at runtime. The workaround is to not set OLEMISC_INVISIBLEATRUNTIME,
	making this a visible control, then setting the control size to (0, 0) in
	the InitControl() function. Added OLEMISC_INVISIBLEATRUNTIME_FIX #define
	to enable/disable this for future investigation.
