[K3] Strange memory/filter behavior

[Randy Moore]

I've been hopping around chasing spots on 10m this morning with my K3
(firmware 4.39/2.73), using DXLab (latest versions).  Sometimes (can't
figure out how to reproduce this), when I jump from CW to USB, the DSP
filter gets set to a very narrow bandwidth and my FL4 (400 hz) remains
selected.

I thought this might be something in DXLab, so I shut it down and was
able to make the same thing happen by alternately doing:

M>V, M1 (selects CW frequency and FL4 (400 hz) with DSP set to 400 hz)
then M>V, M3 (selects SSB frequency and FL2 (2.7 Khz) with DSP set to
2.1 Khz)

The second action above results in FL4 being selected instead of FL2.  
Once I'm in this state, these two steps repeatedly do the same thing.

Now, after the second action, if I use the WIDTH control to fix the
bandwidth (also selects FL2 as its supposed to), then repeat the two
actions above, all is well.  I don't know how I am getting into this in
the first place, but the memories seem to be fine.

Any ideas what's going on?  I first noticed this last night, and I
haven't changed firmware in a good while.

73,

With a little more playing around, I've found that having DXLab (plus
LPBridge) running seems to precipitate the problem, but once I'm in this
state, shutting it down (and all its pieces) doesn't clear it up.  Also,
it seems that when I alternate between CW and SSB, the filter settings
are reversed - I get 400 Hz on SSB and 2.1 Khz on CW.
