We received the Safari beta on Monday afternoon just as everyone else did.
We are in the process of doing compatibility testing, granted this is a
beta. Messenger does use WebKit and Safari makes changes to WebKit for this
beta.
We will work with Apple to try and resolve these issues. In the interim,
Messenger 6.0.2 and Safari 3 Beta do have some incompatibilities.
I was able to use the uninstaller that came with the beta and it appeared to
resolve issues that only reproduced with the beta installed.
Thanks,
Rebecca
