When I try to authorize the beta version (1.2.0b8 as well as the previous beta) on a 10.4 machine (10.4.11) QRecall quits when the password for the preauthorization is entered. The log shows afterward "Missing bundle resource DDOperation.framework.(null) QRecall application is damaged and should be reinstalled" These are after fresh installs on two completely different machines.
Running the release 1.1.4 version on the same systems does not suffer from this issue. I'll just use the release version for now but thought I'd let you know. BTW, I do not have this issue with the beta on 10.6 (10.6.4) machines.
