[Elecraft] KX3 CW Key Sluggish Response

[Sanger, Joseph]

My KX3 is behaving unusually this morning, so much so that I cannot use it for CW (I normally send at about 25-30 WPM; I now cannot send more than about 12 WPM).  The first character is beginning, I don't know, about ½ a second delayed from when I press the paddle (both dit or dah) and extra dits/dahs seem to occur beyond when I stop pressing the paddle, causing enough confusion in my brain to obviate my sending readable cw.  It's not the paddle itself; the behavior is consistent even using my  Begali outboard key.  Adjusting the QSK delay makes no difference (really didn't expect it to as that delay is the 'hang time', not the start time).  I don't take advantage of iambic modes (although the mode selected is 'A').  Any suggestions would be welcomed and appreciated.

I should add that I just updated the unit to the latest firmware: MCU 1.12 / DSP 0.94, but the problem's relation to this may or may not be significant.
Thanks
