Hello. I have probed lablgtk with included examples. I think it is curiously slow, compared to same exmples of gtk with Perl, Python or Ruby. But ocaml is a very fast script language, faster than P, P and R... Have you any idea of this?. Examples where I see difference are, above all, those where there is more computation, like creation of NoteBook in testgtk.ml Greets. David
