[OpenLayers-Users] Mouse position control

[Alan U]

I take it all back (almost!)
There isn't necessarily a problem with the code, but I always have my mouse
on fast pointer movement. This was never giving me a mouse-movement < 2
pixels.

DOH!!

Turning down the sensitivity of my mouse and the code works (of course). It
only updates the control display if the mouse-movement is small enough and
mine wasn't.
Therefore, the default granularity should be raised or anyone running the
examples/default code will see no feed back from the mousePosition control!
My final points about not being able to get latlong values when moving the
mouse slowly are rubbish too.

Alan (gently kicking myself)
