I think this is really an problem with the Opera web browser. I am not able to get a consistent result. Sometimes it will load the page fine, other times it will stop on the loading screen.
I have tested this on a few different computers all running Opera 10 using the following steps.
1) Open Opera
2) Go to Tools -> Delete Private Data.
3) Browse to one of you pages.
4) after it loads, refresh.
5) I repeat the refresh step about 5 times.
I have repeated these 5 steps on multiple computers with different results each and every time. Sometimes it will stop on the loading screen on the first refresh, other times it will stop on the loading screen on the 4th refresh, or the third. I cannot get a consistent result.
