   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....
