Has anyone a idea on how to fix it? If you need the full *dsl to give me so=
me=0D
advice, tell me and I'll send it off the list. I'm starting to learn C, so =
please=0D
don't blame me for not knowing how to programm in such a low level thingy. =

would appreciate it if you could give me some links to an introduction to "=

Thank you very much!=0D
