>Dear Hilmar,
>Thank you for the answer. I'll try it. Btw, sorry for confusing you with my unrelated questions...
Well, they seemed unrelated to me. It is not that you confuse me, and personally I don't mind much. But I just wanted to point out - in case you were not aware of it - that this rule exists, and it has a good reason for it: threads are less confusing if there is a single topic throughout each thread.
Difference in opinions hath cost many millions of lives: for instance, whether flesh be bread, or bread be flesh; whether whistling be a vice or a virtue; whether it be better to kiss a post, or throw it into the fire... (from Gulliver's Travels)
