Hello Olivier

I ran the same code with OS X 10.4.8 (GCC 4.0.1) and ROOT ver. 5.14. Unlike the SL 4.4 environment, the code detects a signal and breaks. If I comment out the line of SetTopMargin, it runs. It seems that it depends on machine environment?

$ g++ tmp.C `root-config --libs --cflags` -bind_at_load $ ./a.out
