Andreas Schwab commented on Wolfram's email with: And Wolfram replied: Therefore your hack might be the better idea. If you still can reproduce it, you've got to decide yourself which hack works really better. Sorry, I don't have time to help investigating this - I should spend more time on my thesis :-(. But I'll try to keep you informed. Andreas -- Andreas Jaeger aj(a)arthur.rhein-neckar.de jaeger(a)informatik.uni-kl.de for pgp-key finger ajaeger(a)aixd1.rhrk.uni-kl.de
