Hi, As it's my first post, let me thank all the macromates guys and the textMate community for the great work done already. So, Thank you all!
My work led me to edit my own (LaTeX) templates, and for the first of them, I pressed an uncountable number of times that precious "Test" Button, to see if everything was OK. I noticed a few things: 1) In my opinion, there should be a kb shortcut for that button. 2) Bug: It happened sometimes that the modifications made to the script and/or to the template itself were not taken into account. It generally does not happen at the beginning of the template building session, but once that famous "Test" Button had been pressed a number of times.
Notice that closing/reopening the bundle editor window solves the problem.
It's up to you, now! Thx, Xavier C.
