Hi Maria,
I cannot reproduce your problem. I cannot use your macro
as it contains empty histograms.
I tested a similar code with real histograms and it works OK.
There are a few changes between 2.22/09 and the current version
regarding clipping in the pad, but a priori nothing that is directly
related
with the C option.
Please send me a short macro with your histograms. I can check if
the symptom persists with the latest version.
