Leopard issue - not OW specific
 

After updating to 10.5.1, it appears my system has a permissions error that is causing files downloaded by OmniWeb to be saved as owned by root (group is me). This is almost certainly an OS X issue and not an OmniWeb issue, but within OmniWeb is where I first noted the problem. Fixing permissions through DU does not rectify.

Hello, sorry you're having trouble here. This isn't really something we've seen reports of before. If you create a new account on your machine. Log into this new account. And try downloading something through OmniWeb, do you still see the problem?
