Be sure to send in the crash report generated, and cc
omniweb@omnigroup.com on the email to make sure someone takes a look at it.
When you wake it up after connecting to the external monitor, are you using both monitors or just the external? Has OmniWeb always been launched when just on the laptop screen, or can you get it to crash after launching on the big screen, sleeping and disconnecting, waking on only laptop screen, sleeping again and doing the connect/wake again? What happens if you wake the laptop first, then plug in the external display?
