When I go to the end of my log and scroll backwards through it, I get an error when It is trying to go to the first page and the start item is less then one (I was at 18 to 48 and I clicked the < link). I believe that the code should be looking to see if the first record will be negative and if it is, it should be set to 1 and then the end number of 30.

Fixed in SVN. The last page button now moves to a page that also starts at a multiple of 30.
