I know where you're coming from, don't worry!
Each iteration of LM is getting closer to being a 'perfect' substitute for Windows, but little annoyances like
this really can be a deal-breaker.
I think part of the issue is that too many developers are spread-out across so many desktop distros. Having
a huge choice of Linux desktops is fine and dandy, but do we really need 4 different groups of devs hammering
away on 4 flavours of Linux Mint?
I've tried them all and can see no reason to chose KDE, Mate or Cinnamon over Xfce (I'm sure others would
say exactly the same about their chosen desktop, but that's a whole other can of worms!).
I'd much prefer simple stuff like mouse-wheel scrolling to work!
