Since the 8.0.10 update I have this problem:
Drag one audio file from windows and drop it into cubase:
the mouse wheel don´t works. (Track scroll and zoom in / out with Ctrl + Wheel)
If I click outside cubase (in any window or desk) and then click again into cubase, the wheel works fine.
For my work, I do this actions constantly and I lose a lot of time with this bug.
