Thread Wont Scroll With Mouse Wheel Once Loaded

[JAS-25T]

So, I've got this weird thing, only on my home PC and only on SAU threads and only when it's fully loaded.

It wont scroll up or down using mouse wheel. I can click on mouse wheel and move up or down, and I can use arrows keyboard or slider on side of window no problems.

just the mouse wheel.

IE

Win 7

Microsoft Wireless Mouse 1000

SAU forum thread pages only when fully loaded. during loading I can scroll then it stops when its loaded.

the forum pages scroll fine. Only threads.

Oh AND!

when I click on next page of a thread and any consecutive pages, it works fine, even if I go back to the page I first loaded its all sweet.

Only the first page I load when opening a thread.

and....Only when I use the open first unread post button OR the title of the thread from the forum homepage (which has the same effect)
