OK, now I see something strange, it appears that something strange is happening. Sometimes when I click on links, it doesn't work and I get a target page like this:
http://lavag.org/topic/10268-portal-page-not-working/#entry61568
This ends up being the first page of the topic, so the anchor "#entry61568" is not found (since it's on the last page of the topic)
But, then I'll click the back button and click on the same hyperlink and it will work, taking me to last page of the topic:
http://lavag.org/topic/10268-portal-page-not-working/page__pid__61569__st__0entry61569
In this case the anchor "#entry61568" is found and it works correctly.
I'm observing the same behavior on both Firefox and Chome.
