Thanks a lot for testing. Of course it did not come to my old
and feeble mind to test with an older VM, even after Phil told
us that these events where not sent when he implemented mouse scrolling.
(Sorry, at least I should have thought about it)

So what will we do now?
1. Change the documentation to point to some working VM
2. Keep the code, but disable the setting and add a preference
    like "Focus follows mouse"
3. Carefully test a bunch of VMs and enable the setting
for those VMs known to work.

The later is obviously the right thing to do,
but I don't want to invest too much work and would prefer
option 2. I want to change that preferences menu anyway
to use check-box-items that give visual feedback about
the option activated. "Focus follows mouse" is the
one that is really bad now.

Again just my 0.20,
