Thank you for your fast and helpfull replies! Autostitch did not start in a first attempt, because I lack Wine - I guess I can just install it with Yast, but there was a Wine-symbol and the name was shown in the task bar, does that mean anything? (

Upon installation of Qtpfsgui there was an error with the "One click install"*, but downloading the .rpm-file worked well. Thank you very much!
Best regards
Ungua
