Comment 18 for bug 147230

I suggest that decision on the action for this bug should only consider the behavior regarding scroll-wheel over the desktop and should disregard the (buggy) behavior of scrolling over "dead zones".

The "dead zones" bug, mentioned by Jeffrey Baker on 2009-06-15, is actually already reported here:
Bug #277195 (Mouse scroll wheel moves between desktops when over parts of application windows)

As suggested there by Lightbreeze ( https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/277195/comments/10 ), these are separate bugs. Clearly, though, turning off scroll-wheel desktop switching would only _hide_ the effects of that bug until a user turned it on somehow.
