I am operating my Flex 6500 remotely using Version 2.0.17 and I am unable to change to 40 meter band by selecting 40 using the band tab. No problem selecting any other of the bands (4 thorough 160). However, if I am on another band with an open slice, and I type in a 40 meter frequency (for example 7.200) in the slice's frequency window, it will immediately move to the 40 meter band with no problems. It will just not move to 40 meters using the band tab.
When I am on another band and I do select 40 using the band tab the slice disappears and whatever band I am on at the time remains displayed. I have tried doing this using a VPN connection and the problem is identical.
