I've done this with mintty on my machine as follows:

I assume the line for X apps would be the similar. Note that you have to 
put the same line in TP4table.dat, then kill and restart all the TP* 
processes. One of them (sorry, can't remember which) is the "parent" 
process and will start the others if it sees they're missing.

Good luck!
