Well I just tried it again twice, on a different PC and the same thing happened.
First of all I have to say, my BB is being pretty maxed out at the moment with UL to torrents so my internet connection is not as fast as previous or what it's capable of. But fortunately the PC is still as responsive as usual.
The fist time I lounged around the main page for a very short while before clicking on the actual page I wanted.
Then after a short while it all started to happen again, without clicking on anything.
Except this time probably for the reason above I was able to exit the net.
On the second occasion it did the same thing again but not until after this time I had opened the photo gallery to view the pictures and then clicked the red X to exit the net.
Again, probably due to the slowness of my connection I was again able to click File & Close.
On both of these occasions it only opened about 20+ pages.
And again PG2 was blinking like mad with blocking only what I consider to be the usual advertising.
However on all occasions there was a pop-up warning which I ignored.
If you or any one would like to try it the page concerned is:
Till Death Us Do Part
http://www.imdb.com/title/tt0437072/maindetails link to main site only.
That is the main page for the series where nothing amiss seems to happen, the next page to select is the third link down (1969)
But on your own head be it.

edit.
It just happened again only this time when just checking the above link was working.
(Which is the same link I have used for a long time)
This time is was a hard re-boot job.
