Question #1:
	Why API-calls use stack instead of registers?

Question #2:
	 I my program I have a dialog box which has one list box(in
	which drives, directories and files are listed) and Enter and
	Cancel pushbuttons.
	 The problem arises when I am scrolling	thru the list and
	press <ENTER> when I want to change drive/directory or read in a
	file. Enter generates LN_ENTER which I process and DID_OK
	which I process. But there is no need for processing the
	DID_OK msg, because both call the same subroutine.
	 At the moment I have a flag indicating whether to process
	DID_OK and it works. Fine.
	 BUT in the sample program(graphic2) which came with Toolkit
	there are no flags.

	 What do I do wrong ?

	I hope there is someone who can help me...

        When I feel myself slowing down , I know for sure that I've been
    here before, 'cause if it isn't an action replay, what else could it be.
