 	Sep 14, 2007	REF: OMAPS00145866  Adrian Salido
 	Description:	FT - MMI: Wrong trace class
 	Solution:		changed event traces to function traces because the information content of
 				this is low for non-MMI people and against TI coding convention.
 Nov 05, 2005	REF: OMAPS00049571   Sumanth Kumar. C
 Description:	eZi Text function is not working
 Solution:		current_mfw_elem variable is updated when any of the elements
 such as window, keyboard, timer, etc., are deleted so that the
 current_mfw_element does not point to element that has already been freed.
 	Feb 28, 2004    REF: CRR 25608     Deepa M.D
 	The mfwEorc is made const.The changes will be present both in Color and Golite build .

 Description: BMI: memory leak in mfwFree/mfwAlloc ??
 Solution: Trace output to print memory address and size freed
 modified in function mfwFree()
