[tlug] Linux Mint 18 window behaviour

[Brian Chandler <brian@example.com>]

Probably an elementary question, but having moved to a new installation 
of Mint there are various annoying things that I can't control, or 
rather can't find where to look to find out how.

(1) In response to a probably involuntary action by me (failing to hold 
the mouse exactly steady, accidentally touching a key, whatever), there 
is a silly sound, and the window I am looking at resizes to the top half 
of the screen. I never want this to happen, so where can I look to turn 
it off?

(2) Margins on printing. This is a wide-ranging problem, that lots of 
people are trying to be terribly helpful, so when they are responsible 
for processing a page image, they add some margin. I want to be able to 
control things myself, so for example if I have a piece of music (in 
Musescore) with the Page Margins set to 10mm all around, then I want the 
PDF generated, and the sheet printed to have 10mm margins all round. 
Same with page images generated in HTML. I seem to spend amazing amounts 
of time, and wasted ink/paper, just going round trying to kill settings, 
in the printer, the paper selection, the browser, etc. Does anyone have 
any brilliant thoughts on a way of avoiding this? For example, I wish 
the paper size to be A4 (which is the size of the physical paper), not 
"A4-with-some-ideas-about-leaving-extra-margin".

Grateful for any suggestions.
