We just upgraded to SW2011 SP4 from SW2010 and now Circuitworks is broken.

When I try to export a PCBA to Circuitworks, I get the "Select orientation..." diaglog box as expected.  I pick the top face and hit Continue.  The diaglog box disappears and pops up again.  I select face again, and hit continue again, and it pops up again...ad nauseum.

Hitting "cancel" opens up CW without exporting any geometry.

Anybody else see this???

Trying variations on the "don't prompt me for known assemblies" option yields the same behavior.

Thanks!
