PTT can casue the LPT port to become more sensitive to RF 
than it is without it.

You may need to put some chokes on the CW/Paddle and PTT lines 
going intot he computer.  You can also try truning off 
the PTT signal in TR-Log and see if that has an effect.

I would suggest you try to figure out how (what cable or cable location) 
is causing the RFI - and fixing it at it source or filtering the 
line coming into the computer.
