Do you have
>IF llCancel
> EXIT
>ENDIF
in the outer loop too?

I just ran this code as test, and worked as expected:

local lnStart, llCancel, lnKey

set escape off
lnstart = Seconds()
do while .t. and (Seconds() - lnStart < 5)
	lnKey = Inkey()
	if lnKey = 27
		llCancel = .t.
	endif
	if llCancel
		exit
	endif
enddo
? llCancel
