Chad,
I had used the Contacts popup as well as others, with the same results. After further testing I have isolated the problem.
If the destination tablink is on the same tab as the originating screen, it works. But, if they're on different tabs, it doesn't.
In my case I was going from the Activites List on the Activities tab to the customer screen, as mentioned previously.
That should help to get this fixed.
thanks,
Rolf
