problem with windows version, not the mac version.

I am seing strange behavior after programmatic pauses (@pause)

on the first extruding move, after i continue to print, it absolutely gushes plastic, perhaps ten times more then it needs too.

the resulting blob can easily ruin a print

has anyone seen this?, has anyone overcome it?
