The file association for .tbc files on WNT is incorrect, it currently reads:
...\prowish83.exe" "%1"
it should read:
...\prowish83.exe" "%1" %*
The current association does not pass in parameters to the compiled Tcl script.
NOTE -- this was originally tcl-Bugs-230419 and is being resubmitted here at Andreas Kupries
request.
(We really should be able to move bugs)
