[p2/b6] Very minor zoom bug.

[Dave2]

This is so unlikely to happen that I wondered whether to even report it, but it has happened and it has confused me.

If you press ctrl+z just as the level is loading (easy way to reproduce this is to wait for the black screen to come up after clicking a location and hitting ctrl+z repeatedly until it miminises), when you restore the game it's zoomed in. You have to press z to unzoom (middle-mouse doesn't work, which confused me at first).
