I tried again today. Removed all tabs, closed down OWB, started it again and went to that HP. CPU went to 100% for over 15 seconds, and memory dropped during this time from 793 MB to 362. Not until it reaced the lower level did the CPU drop to normal levels. Clicking on other links also drain the CPU for maybe 10 seconds, but memory don't drop below 200 MB.

Maybe it has something to do with the G5? I have a G5, 2,7 GHz with a Radeon 9600 Pro 256 MB VRAM and 1 GIG RAM. I have not experience the same problem with other HP:s.
