[line eater fodder]

Hello,
	I am a recent refugee from the PC world so I am a little
uneducated with respect to Macs etc., and I would like to ask a couple of
questions.  I am an experienced programmer so I can handle technical
descriptions.  Please give references were appropriate if you know them.
Question one concerns a stock Mac Plus, two about the Apple Laser Writer.  

	1) Every once in a while a particular program will cause the disk
that it resides on to become the startup volume if it is not already. I
see this because the disk icons on the desk-top get swapped so that the
afore mentioned disk is in the upper right corner. How does this come
about? Can I turn this "function" off and on at will? 

	2) About the Laser Writer... I notice that there are two kinds of
yellow light blinking.  A 'single' blink and a 'double' blink. It appears as
though the double blinking occurs during timeouts and Postscript function
definition transactions, while single blinking occurs during function calls
(like during the printing of a document).
	Does anyone have a more concrete definition of single and double
blinking? 

Any help would be appreciated.
