A few days ago we had a thread about how Imwheel cause Galeon to ignore settings and scroll one page at a time. The solution we had at the time was to kill imwheel. I just ran across this better solution where you configure imwheel to ignore Galeon. Edit your imwheelrc file to include "^Galeon" @Exclude The imwheelrc is most likely located in /etc/X11/imwheelrc. Then restart imwheel. -Sevatio
