absolutely no problems here
multiple macs, running 10.4.x and 10.5.x, all updated to the new QT, no problems.
Of course, it's true that I stopped using Stuffit years ago precisely because one or more Stuffit component would cause problems with system updates... <checks records> the last version I paid for was Stuffit 7, and it's up to at least 12 now. I'm still on their mailing list, though.
