Ports have changed...
Just turned on the Flex 6500 after being off for a couple of days and noticed in the CAT window (v1.2.4) I now have COM6 where before it has always been COM4 and that's the only one selectable as nothing else shown.
In the Serial ports tab available ports show COM4-14 COM5-15
I had in there originally COM4 and COM5ptt that has now gone no more ptt.
Port maps show COM4, 5, 6
Just did a windows 7 x64 update rebooted the computer as well as the Flex 6500 and still shows COM 6 so deleted all virtual ports and started again and now back to COM4
Started SmartSDR moved window to make it smaller and it's froze, though I think this is a known problem reading the release notes...
