Hi Satoru, I must admit there is no way to do this (even through hacks or I've missed smthn?). I think we need to ask Rene to implement some security code for this class. Anyway it is very useful interface and some attention to it from the developers' side would be great. (I know ROOT team is not going to develope HBOOK interface.) So, Rene, would you be so kind to include some code to be sure that Hbook file is open? Best regards, Stanislav.
