So, since I woke up today, I haven't been able to scroll on the forums using my mouse wheel. Haven't encountered this before and it works on other sites.
It's a bit irritating so I'm asking here, anybody has any idea why this could have happened and how to fix it?

It happens to me when I accidentally click with my scrolling wheel but I can't replicate it intentionally, its just kinda random. Closing your TB tab(s) and opening a new one fixes it for me.

Thanks, that worked.
