Mozy & My Living Desktop
I've had the same issue with Mozy on my iMac and MacBook since upgrading to 10.6. I'm currently exchanging e-mails with their Tech Support but haven't gotten anywhere. Curiously, I had the same issue on 10.5.7 before switching to 10.6.
On a separate note: My Living Desktop doesn't seem to work with 10.6 as well. I just now sent an e-mail to their Tech Support.
If I hear anything of value, I'll be sure to post it here.
Take care,
Bob
