Next time this happens--would you please try typing the following command in a terminal window:
it will then capture what OmniWeb is doing every 10ms for the next 2 seconds and write a file
Code:
Sampling process 10922 each 10 msecs 200 times
Sample analysis of process 10922 written to file /tmp/OmniWeb_10922.sample.txt
Please then send feedback (Help->Send Feedback) and include the file.
To include the file in mail quickly, click the attach button and when the open sheet comes up, type a '/'. The "Go To Folder" dialog will pop up and you can finish typing "tmp" and hit return to go straight there.
