Because this forum is weird sometimes. So I thought there might be space for a place to mention curiosities, either to find a way round things or just to establish whether it's the site or one's own computer that's the problem. My latest: sometimes when I try to paste links, they're invisible. Not only that, the blinking text cursor disappears. Only after I've given up and posted, intending to edit in the link later, do I find that what I thought had been failed attempts to paste had succeeded, resulting in multiple links. Anyone else notice this? It could well be my computer, as it's problematic in its own sweet ways, but it only seems to happen here.
