I´m very sorry for the problems you have with the programm - I suppose the problem is with Tiger (probably I not toggled the switch for the 10.4 SDK in Xcode...
I´m on a work trip this weekend but hope to release a new version with some of the issues fixed in the beginning of the week.
Thanks a lot for your feedback, thats exactly what helps a lot...
Your issues will be on the top of my list for the next working session (maybe I need some help with the icon - graphics artwork is not my very best skill
Best regards, Markus
