Hi Kurt!
Answering a message from Kurt Wismer to Klaus Kulbarsch:
 KW> self checks stop anything, they just make certain activities more
 KW> difficult... real security stops things like the above though...
Many thanks for all those real worthy tips - I do know (and use!) them for 
myself since quite a long time ;-).
Nevertheless: a good self check is, in my opinion, an absolute *minimum* for 
a scanner which it's programmers wish to be worth to speak about.
Greetings from Wiesmoor (Germany)
