I may be one of the last Panther/TM user but anyway...
As I told Allan on IRC, r1070 completely breaks 10.3 support and TM crashes everytime I try to see what's in a bundle, either through menu or the gear menu at the bottom. Am I the only one?
I reverted to r1060 and when it tried again to update itself, I clicked Cancel and the window stayed up with both option greyed out. Only way to remove it was to quit.
