wat i m doing i send u the whole code and i call the function twice in the way
that the selected item text frm the list and store text first in the variable
item and the i display it on the button label. after that i free the item
variable.but it create some proble that why imake the item variabl as globle
and free it at the time of exit the application and it wrk fine.
As u say i also try to make call TodayAppList(0) when i exit the application
with applstop(); even it has the same problem. and even create 1 more free ptr .
