1st	I apologize for using capital letters, I originally thought that they
	are meant to put emphasis on a word but found out later that writing in
	CAPITALS are considered as SHOUTING.(I use them here still as highlight
	though.)

2nd	I know that OS/2, Windows do not have _real-time_ scroll-bars in _all_
	applications. However, I do find that OS/2 and Windows 3.1 have
	_real-time_ scroll_bars for desktop windows and file dialog windows.
	(It would be a real CPU hog to have _real-time_ scroll-bars for
	graphics-intensive applications, I concede) 
		Since normally the desktop icons are not too complicated, it
	might be possible to have _real-time_ scroll bars for the mac, this
	does help not too little as it gives you precise control over when or
	where to stop when you are, say, searching over a long list of
	filenames or icons.

3rd	Someone mentioned that the newer version of Alpha (text editor) does
	have a _real-time_ scrolling feature. I tried it and find that it is
	not _real-time_ enough(on the school's IIcx, IIsi), perhaps at present
	_real-time_ scroll-bars are not yet suitable for within applications(
	someone on the net even reported he has to wait a moment every time he
	scrolls _real-time_ on his NeXT)

4th	I orignally saw this nifty-feature on a HP-PARC 730 workstation and
	like it very much(very helpful). Later, the Quadra came out and they
	were in the WorkStation class but yet have no such feature built-into
	the OS. I was slightly disappointed, since NeXT has it.

Anyway, I admit I am too meticulous on this, but personally, I will think twice
buying the Quadra(assuming I have the cash) just for the lack of this feature.
However, if I were to buy the MacIIsi, I won't mind because I perceive it to be
a sub-workstation class machine that's not supposed(able) to have _real-time_
scroll-bars, but I do envy those Windows 3.1 or OS/2 users for having at least
in the file-open dialog box and desktop windows the ability to scroll in
_real-time_.
