WHen I click on this link/Last Page I see a thread....
Short answer - It's a Display issue. The forum "defualt" threads to a page is X number of threads. The User can adjust this number in their CP. Screen resolution also plays a part. 1024X will disply more that 600X will.....Even the size of the monitor plays a part in how pages are displayed....
If you're happy and you know it......it's your meds.
