// HISTORY:	 
// ========================================================================== 
//			1.00	02 Oct 1998	- First release version. 
//			1.01	05 Oct 1998	- Fixed offset bug to use GetSystemMetrics(), 
//								  instead of hard coded values - 
//								  Todd Brannam (tbrannam@msn.com). 
//			1.02	02 Nov 1998 - Added OnSetFocus(), OnKillFocus() and 
//								  modified OnPaint() so the control remains 
//								  beveled until it actually looses focus - 
//								  (Vachik Hovhannissian). 
//			1.03	02 Jan 1999 - Renamed class from CJComboBox to CCJFlatComboBox, 
//								  changed DRAWSTATE to enum, removed method Offset(), 
//								  and replaced with a direct call to ::GetSystemMetrics(). 
//			1.04	22 Jan 1999 - Fixed accelerator problem reported by YOSH YAMASHITA 
//								  (yosh@muj.biglobe.ne.jp) with Matt Weagle's solution of 
//								  overloading PreTranslateMessage(). 
// ==========================================================================
