This release - doesn't generate an errorlog.txt file entry when an invalid slider # is specified in a command from another application (tnx to Mike ON6ML) - correctly handle updates to VFO B that specify a transverted frequency (tnx to Stewart G0LGS) - doesn't lose transverter selection when tuning across a 1 mHz boundary (tnx to Stewart G0LGS) - when controlling an Icom IC-7600, IC-7800, IC-7850, IC-7851 with current firmware, requests the Primary VFO frequency using the old opcode 3 command rather than the new opcode 25 command so that external devices can successfully track the transceiver frequency via responses to the opcode 3 command (tnx to Greg NZ6E) - provides a TXMeter command that from within a user-defined sequence sets the Xmit Meter selector (Configuration window, General tab, Radio panel) to the specified setting (tnx to DAN KC2STA) - provides an IFRADIONAME command that alters the flow of a user-defined command sequence based on the name of the currently-selected primary transceiver (tnx to Jeff AC0C) - provides a new Perseus setting in the “Secondary CAT Port” panel’s Protocol selector that is identical to the Icom setting except that the Perseus setting sends mute and un-mute commands to the Perseus when the primary transceiver switches from RX to TX and from TX to RX respectively (tnx to Hubert HB9JND) - with the "use multiple monitors" option enabled, relocates to the primary monitor any window that can't be displayed on any monitor - works around Microsoft OS version reporting defect so that Windows 10 is properly reported in errorlog.txt file startup headers - updates the CommandSequences.htm and Configuration.htm documentation files Commander 12.0.0 is available via the DXLab Launcher and via 73, Dave, AA6YQ
