[OpenLayers-Users] drawing shape gets offset when window expands

[Burgholzer,Robert]

Chris,
Thanks for the response.  I am using OL 2.6.  The issue occurs not when
the map window is resized (it stays the same), but when it's location is
moved over on the page to accept a larger block of text in an adjacent
table cell. 

I currently do not have the ability to demonstrate on an external server
(some time tomorrow or later today I will get that going).

Thanks for any insight,
r.b.

I'm somewhat surprised that this is happening in OL2.6, but you didn't
mention what version you're actually using... so I don't know what
you're actually using. 

Any time your map size changes, call map.updateSize(). This should clear
out the event caches, and make your mouse position/line drawing correct
again.

Reproducing a small example where it doesn't if it doesn't work would be
good.
