CPU usage...

[Laurent Jumet]

Hello !

I'm using Opera10.01 with XPHomeSP3, and I notice that sometimes Opera wastes about 40% of CPU usage while there is only one tab open, no downloads, no Ports opened, JavaScript may be OFF or ON (doesn't matter).
Why?

The only thing I could say but I'm not sure, is that this seems to happen when FlashPlayer has been previously used, but its Tab has been closed.
Closing Opera and re-opening it, restores that CPU usage to the same level. Seems that Opera is trying to do a job that never ends and without any external evidence of it.

Does version 10.10 correct this?

Some example of Stack for thread using 45% CPU:

What's using 50% CPU, without any network activity?
