Does it work at all if you do the normal combination? Control + Mousewheel to try resizing the page?

Or does that not work either?

That worked on this webpage, but not my yahoo mail, like it usually does.

I opened yahoo mail on a new tab and now it's working there.

The mouse wheel is working there too now, but I tried opening this webpage on a new tap and it didn't work there.

was your cursor in the same place when you tested it? It has to be within the window(below the tabs etc) to make it work. just checking

Yeah, doesn't seem to matter where on this page I try the wheel, wont work. It's now working on all the other webpages I try. Seems this one now is the issue, lol. Maybe we can just forget about it. Thanks.
