// This class fixes the sizing bugs in MFC that calculates the 
// size of toolbars incorrectly for modern toobars (comctl32 version >= 4.71) 
// It also contains a number of wrappers for function that CToolBar doesn't 
// have (so you don't have to use GetToolBarCtrl). 
// 
// Generally, you should use CFlatToolBar instead of CFixMFCToolBar (even 
// if you're not using the flat style), but you can use CFixMFCToolBar if 
// all you want is the sizing fix for MFC tooblars.

	// the width of the toolbar. If, however, you have dropdown buttons, then the 
	// width of a vertically docked toolbar will be too narrow to show the
