[OpenLayers-Users] question about the measure control

[Aaron_Gundel at sjwater.com]

Hello all,

I have a question about the measure control in openlayers....  I noticed 
today that after we upgraded to Openlayers 2.8, the behavior for the 
control is somewhat different than it was in 2.7, with the primary 
difference being that if you're "in a hurry" so to speak and don't make 
your clicks slow and deliberate, an invalid distance appears on the 
initial click.  I checked and it doesn't look like its just me -- it 
happens on the example page also. 

http://openlayers.org/dev/examples/measure.html

Click while you're in motion and it's fairly easy to replicate.  Your 
initial distance will vary based on...well I'm not sure, but the distance 
is not zero as you might expect.  Any thoughts on what might be causing 
this behavior?

Aaron
