Hi! Could you give us a hint, which expression caused the crash? I tried several expressions but cannot confirm. Eike
Well, I think it was a logarithmic rational expression, I don't remember exactly how it was but I'm sure it was something like ( log(...) + [...] ) / ( log(...) + [...] ). Hope it helps! Best regards,
