Hi Herbert,,
That's pretty much my experience, too with JABB. However, even thought I downloaded the update for GPO, I did not install the update. There were things showing in the update intruction file that were not showing the same way in my GPO. But I did have the instruments under the instruments tab, so I did not take the chance on installing it because I thought it might take me backwards instead. It is confusing.

BEst,
FRed
