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.
