Hmmm, I guess we could quickly gather dozens of well known bugs in this thread. Before doing so: Is there anyone who would like to set up a database with online access for bugs (including workarounds) in Mathematica? Perhaps the existence of such a database would force WRI to include it into their support section in order to get it under their control. Not the best motivation for a better bug documentation by WRI but at least it might work. Greetings Martin Kraus
