Hi,
With both this beta patch (73251) and the one before (73246) when I zoom in using a scope...it will un-zoom all by itself without me touching the button.
At first I thought this was my mouse dying....but tried a brand new mouse and the same thing happened. It will randomly un-zoom. Not nice!!
Went back to 72967 which I happened to have on my machine and it stopped....so using that.
Weird that no-one has reported this!
