Scroll mouse support. What happened????

Im using the new version 807 RC1 which seems to have lost scroll mouse support.
In old versions, whilst in full screen, you could scroll the volume up and down, out of full screen the window size would scroll large to small. These were some of my favorite features :(

Is this intentional? An instalation error? Something else?

Im not realy complaining as its a free product. If it is intentional Ill go back to an earleir build.

Thanks.
