  Hi Joern,

  You are right. I had to replace the default histogram graphics option "" 
with "hist" in order to be able to change options on the fly (typing a new 
option in the Option text-box + Enter) since without it the behavior was 
quite strange. Unfortunatelly, this does not work for TH3 and I will correct 
it very soon, togeather with a few other problems.

  Thank you for reporting the problem and please keep me posted if you find 
anything else.

 Best regards,
Andrei Gheata
