This release - reports correct frequencies in the Stations Heard and Channel Monitor windows if the PSK Transmit panel's Split box is enabled - tolerates an undefined DXCC entity in PSKDisplay.SetReceivePane without generating an errorlog.txt file entry (tnx to Art W2NRA and Wolf DK1FW) - after the operating mode is changed via the Main window's "Operating Mode" panel or via a directive from another DXLab application, will not initiate an operating mode change in response to a transceiver mode change for 5 seconds (tnx to Art W2NRA, Wolf DK1FW, and David K0COP) - ensures an accurate distinction between Operating Mode changes triggered by transceiver mode change and Operating Mode changes triggered by a user gesture or directive from another DXLab application - doesn't execute operating mode changes triggered by transceiver mode changes until initialization is complete (tnx to Art W2NRA and David K0COP) - rejects any parallel port base address greater than 7FF8 hexadecimal (tnx to Paul VE7BZ and George KF7NN) - if DXKeeper is running but a callbook lookup directive to DXKeeper is rejected, issues a retry (tnx to Jamie W2QO) - updates the CWSettings documentation file A special thanks to Art W2NRA for his help in tracking down then "missing RTTY waterfall/spectrum" problem, which was the result of a race condition during initialization; these are the toughest of all defects to track down, and Art came up with the replicatable scenario that made it possible.
