Yes, but there is still the one problem: if you leave the link as the XHTML standard says you must (without trying to open a window), then the viewer can choose to open it in a new window or use the same one - two choices. If you try to force the page to open in a new window (which the standard says you must not) then the viewer has no choice - you cannot include some extra key while clicking the link to force it to use the same one, it will always open a new window - zero choices. How is removing choice from the viewer (and honestly, I don't much care about your business model if it fails because someone dare view a site in the same window - this isn't necessarily directed at the person I reply to by the way) in any way a good thing? Too many sites these days think of their viewers as products that can't think for themselves.
And vesperala? You really don't want to respond in the affirmative to the question "could you be any more condescending and arrogant" - it's not a good thing to be condescending OR arrogant. Besides, teaching someone to middle click is basic. I'm afraid I don't want to say this but: if your members don't know how to right or middle click and don't want to learn, they should go away and make room for more open minded people with a modicum of intellect. I'm not calling them stupid for not knowing something, I'm calling them stupid for refusing to learn. Too many people these days expect everything to be dumbed down to the lowest common denominator, to the detriment of anyone above that. Some people have just never heard of middle ground - it's either dumbed down or nonexistent.
