The case issue occured to me later, but I don't think it makes much difference--acronyms, as you say, are about it, and there aren't that many of them in the dictionary. I'd figure out how many, but the local Linux boxes are all having screaming fits today, so I can't right now (unless somebody wants to tell me where to find the words file on IRIX, which I'm not convinced is there at all).

Thanks for the tip on the screen-saver--might have to try that.
