On launch, OmniWeb shows ONLY default favicons
 

One of, if not THE, principal reasons I like the OmniWeb browser is that I can place a lot of favicons (almost always without text) in the favorites bar.
I currently have 30 of these and they really speed up my browsing.
However, in the last week or so, when I launch OmniWeb, every single one of these favicons has been substituted by the (very ugly, IMO) default favicon.
Now, clicking on one --any one -- of the default favicons immediately restores the correct favicons.
I admit this is not a major problem but more of a minor annoyance particularly when I want to show off OmniWeb to a friend.
Is there any way I can avoid this hiccup?
