And that's a literal translation of an expression, which in Swedish implies 90 degree angles. Not really an expression, you just chose the wrong synonym to translate: r t -> rak -> straight instead of r t -> r tt -> right So, a "right angle" would have been fine. And a "brasklapp" (translate that if you can): BQT writes better english than most Swedes I know, including myself, so I take any chance of correcting him :-) /P
