A recent update more or less completely broke zooming. When now zooming in game mode, it either doesn't zoom, zooms very delayed, or erratically jumps back and forth between different zoom levels even after stopping to use the scrollwheel - makes playing with this mod close to impossible. It is as if it were fighting with the normal zooming or another mod (but no other zoom-related mod is installed). Disabling the mod restores normal (vanilla) behaviour.

@schmorp, exactly. Got this problem too!

Thought things might work better when trying to replace the regular zoom function than it would when I started out making this mod. Turns out there are still a whole boatload of edge-cases that will be extremely annoying to try to fix. Have reverted back to the old hotkeys in 0.1.8.
