[OpenLayers-Users] Bug? Zoom box offset when using large scales

[Holmes, Charles V.]

I've run into some similar behavior that hopefully will be useful in
debugging the problem.  I'm not sure if it's the same problem, but it's
certainly related.

Using SHIFT+drag will occasionally draw the box in the wrong position
like you're seeing with Barend's problem.  Once it tries to draw it in
the wrong position, any future SHIFT+drag will also be in the wrong
position.  

However, by reloading the page, the problem will usually go away.  Once
it draws it in the correct position, I haven't noticied it changing
over into the incorrect one.  When we use the PanZoomBar, it will
always zoom in correctly.

This is almost definitely a bug in OpenLayers ... holy crap, you
weren't
kidding. Something's totally broken there. 

Erik, can you file this as a blocker for 2.5? 

Thanks for the report, Barend. We'll look into this.
