I followed other's advice on this reflector and changed the attribute
on my computer to GUI=0 so it comes up in WIN98's "real" DOS. I just
type WIN if I want to continue loading WIN98, otherwise I can run my
DOS software.

My setup was an MFJ keyer/Bencher key combo feeding an FT-890 with
the internal keyer off.

I experienced this with CT 9.37 using more than one of four I built
and used for XU1A. In my case I believe it was RF getting back in
and keeping the interface keyed. Antennas too close, no real equipment
ground available and a plastic interface housing without bypass caps,
etc. I was ASKING for it! I will be modifying my construction.
I could stop the problem by killing the rig power until the Function
Switch programmed CW was theoretically "over". I could make the problem
go away by turning off the linear and reducing the exciter power or go
to a different antenna/band. I would be interested to hear if there is a
software issue, too. What I really wish is that I'd used v.9.27 instead!
It was not smart to use the newest version for this critical use. Can
we say TIME PROBLEMS....
