Hi David,
the matter for this posting is: I'd like to have some postings deleted 
Seriousley, The last week I started all together 3 threads. Only the last one makes sense because only this describes the solution of the problems which are described by the other two threads. Is it possible to delete them ? (I don't like cyber-waste):
At software/troubleshooting:
"error compiling" when uploading blinker
and
Arduino-IDE on openSUSE 11.2
Thanks, Rafa
