Oddly enough if you look at my posting history you'll discover that I know the guidelines. Specifically, the bit you quote:
Please don't post on HN to ask or tell us something
(e.g. to ask us questions about Y Combinator, or to
ask or complain about moderation) ...
... is talking about not posting to the group questions that are intended for YC or for PG - the "us" in the above excerpt. "Ask" and "Tell" are not part of the culture, they are independent of this.
Moving on ...
My investigations haven't got very far, not least because I've been struggling for the past 6 hours to make my machine usable again. I've given up. I'll just do without flash until someone can tell me how to fix it. The forums I've checked haven't helped at all, although I didn't know of SuperUser. I'll try that tomorrow.
And regarding ESR's recommendations, again, oddly enough I've suggested in the past that people read them, and I had them in mind when I posted, but I am seriously beyond caring. I had hoped someone would (a) recognise the problem,and (b) cut me a little slack.
I guess I was wrong. Pursuant to your observation, I've edited my original submission to give some indication that I have expended at least a little effort already in trying to solve this.
ADDED IN EDIT: The question appears to have been asked in SuperUser and has had no replies. Based on other searches in other forums I'm not surprised, but I'll make more searches tomorrow.
