[Elecraft] An Old Glitch Returns with KX3 firmware version 1.41

I want to report an old glitch that seems to have returned with KX3 FW ver
1.41:
After a band change, and after an ATU match cycle has been run while in one
of the SSB modes, my KX3 will not transmit when the MH3 is keyed.  BUT,
after a simple toggle from USB/LSB to CW and then back to USB/LSB with the
mode button, the PTT button works fine and all is well again.  I don't use
VOX so haven't checked it that way.

This glitch is repeatable with every band change to any band.. every single
time.  It occurs in SSB only . I have had no problem with CW, and do not use
FM or digital modes so cannot comment on them.

This glitch was present when I first received KX3 S/N 125 with firmware
version 0.99   .. Somewhere along the way I reported the problem, but do not
recall exactly when I did so.  I have upgraded firmware on a regular basis
and know that the glitch was corrected with a firmware upgrade several
months ago, but it does not seem to be specifically mentioned in the notes.
I do not recall the specific version in which it was fixed, but I think it
was possibly 1.22, and I am certain that the problem was not present with
versions 1.34 and 1.36.   The old problem returned yesterday when I loaded
version 1.41.

The problem was here .. It went away after a firmware upgrade  . and now
it's back with 1.41.

I just wanted to report it again so it can possibly be addressed.  

I'm also very curious since I don't recall seeing any other mention of this
.... is anyone else seeing this?  ... or am I dealing with a unique
scenario?
