[WriteLog] Band change problem

[Gary AL9A]

During the CQWW DX contest I noticed a problem with WL V10.73D.  When I 
instructed WL to change bands from 20M SSB to 40M SSB by typing a 40M 
frequency in the Call field WL would instruct my IC-756PRO to change bands, 
BUT on several occasions the mode was left set to USB instead of LSB.  It 
didn't do it every time, but enough that it was annoying.  At first the 
audio reception told me something was amiss and I noticed the radio was in 
USB instead of LSB.  On one band change I didn't catch it and started 
calling CQ and was shortly told that I was on the wrong side band.  Rig 
control is via the Microkeyer II CI-V jack, but I've never noticed this 
behavior before.  Any ideas?
