If you are using same version of TR with same configuration,
then what could be different?

The computer itself - possible printer port fault?  By dit-dah
I guess you mean it goes di-dah-di-dah-&-so-on by itself.
Unless your keyer paddles are actually shorted, it's unlikely
that both your homebrew & TopTen interface boxes suddenly
stopped pulling the paddle input pins high internally.

Otherwise, if it is something that Windoze has done, what
have you done to the computer since the last time it worked
okay?
