Hi, I think, we should close this thread! I've copied the working setup from one to the other machine and it's working fine! I'm pretty sure now, there was a problem with my system! Don't know what, were or why.......sometimes the club works better than the scalpel :-) Thanks all for your help! @Till: I didn't got your mentioned reply to my PM to you, but this could be happend due to my mail problems here! Nevertheless, thanks for your offered help! @Martin At the weekend, I will try to upgrade my kolab installation, thanks for the hint! Bye Stefan
