 Description: Symbol screen for AUI editor



********************************************************************************

 $History: AUISymbol.c

	Mar 23, 2005  REF: CRR 28490  xnkulkar
	Description:  Golite- 5-way navigation behaves wrongly while selecting special characters
			   in the text editor screen.The background screen goes blank when the special
			   characters screen comes up.
	Solution:   Commented 'dspl_ClearAll()' to make the behaviour consistent with normal variant.
