Click Mouse Wheel... Now Zooms?

So, up until recently, when I clicked my mouse wheel, it would give me a pan like ability, where I could go all over the map and then click again to get the cursor back. Now, when I click mouse wheel, it zooms in one step instead. Is this a Roll20 change, or was it something I did and don't realize it? I really want the pan back as it was infinitely more useful. Thanks!

I just realized that if I hold Right Mouse button, I can do the same effect. Just stumbled upon it... It actually works really well.

That sounds like an extension in your mouse drivers.  I have a vague recollection of Logitech drivers having a similar sort of feature.

You're absolutely right. That was it. Thanks!
