Slow Inverse Command

I just upgraded to AutoCAD 2006 with SurvCadd 2006 from 2002/XML. The
inverse command now seems to have a significant lag. The system pauses for
about 2 seconds after each click. It only seems to happen when picking
points off the screen. If I enter point numbers its fine. Has anyone else
experienced this problem? I'm running a P4/3.4, 1G ram, 128MB ATI video
card.
Any help would be greatly appreciated.
Thanks
