update--I finally browsed two Acq's (ver 107.2 and 105.3). Most of the time though, double-clicking an Acq that shows QRP% >0 opens an IP tab in the search pane but no search results ever show. Other non-browsable hosts either show the "Cannot browse" dialog or else start the IPtab then close it quickly.

I'm seeing far fewer Acq's: Usually there are 8-10, but now both machines (UP) show only 2 on each. Did the limits on non-LW connections change, and is Acq now counted as a non-LW vendor?
