Use Activity Monitor to take a sample of the OmniWeb process when the app is frozen and send it to OmniGroup Feedback (via the Help>Send Feedback menu option... obviously you'll need to force quit and re-open OmniWeb to be able to do that - hold the shift key to open in a new workspace to prevent the freeze from re-occurring again). Include the URL of the site causing the problems and a description of what you did prior to the freeze.
