Also -- when I posted that msg just above, I clicked "post reply," not "preview" -- but it popped up a preview anyway, and then when I went back to the msg and clicked "post reply" again, it told me I had to wait 4 seconds, blah blah blah, like a double-post thing... so, rather than continuing to do that, risking a double-post, I just selected all the text in the above and copied it, just in case I needed to repost it -- and then hit F5 to update the screen, and the msg was there, no need to do it again
What I discovered with that glitch is that selecting text does have a visible background color, but it's so light, so close to white, that it's VERY hard to see -- that CSS really needs changing, to make it more apparent that text has been selected.
