I wasn't very clear about the annoyances/quirks. It actually involves features/functions not settings. One example is: after I've drawn a few lines, when I click on one of the drawing options on the right side (i.e. "Construction Line") I no longer get the full display of options (i.e. "Horizantal", "Vertical", etc.) for that function. I have to save, close and re-open for the button to work as it is supposed to.
I remember reading complaints about these quirks some time ago, w/regard to v. 17. I was assuming they'd be fixed with v. 18, but here they are again.
So, I was wondering if 18.1 and 18.2 fix some of these quirks - if not, just what do they accomplish?
