Hi,

I have noticed a problem with Google Maps API v3 when it comes to zooming
in with the mouse wheel. The bug is reproduced as following:

1: Goto a Google v3 map :-) Ex.
https://code.google.com/apis/maps/documentation/v3/, scroll to the first map.
2: Zoom in as far as you can with the zoom bar. Have a road or something in
the viewport.
3: Try to zoom in even more with the mouse wheel. The map will try to zoom
in one more step, but the figure out that it can't so it seems to be
zoooming out again, but when it does this it will skip and you will not be
at the same position you where before you tried to zoom in with the wheel.

I am on Linux, using Firefox 3.5.3 and I have also the same error in Opera
10.00, build 4585.

I'm seeing this as well... random jumping around while using the scroll wheel. (I
also see jumping even when not going in past max zoom.)  I've seen it on FF3.5 and 
Safari 3 on both WinXP and OSX10.6.

It feels as if it's something to do with how the map attempts to zoom in on where the
mouse is, as opposed to where the center is. I can see the initial tile expansion
zoom up whatever was under the mouse, but then when the tiles snap in, I'm miles away.

I have also see the same thing happen when doing an explicit setCenter(). I have a
bunch of markers, and set each's click event to setCenter() to the same LatLon
variable used to set the marker's location in the first place (the variable is unique
to each marker creation due to being in a closure). The setCenter() is then followed
by a setZoom(15) if the current zoom is wider than that. Often, but not always, the
viewer is sent somewhere 1000s of miles away.

Here's my application, which exhibits the jumpy behavior:

Indeed. Zoom seems now to be correct. Thank you! :-)
