Louyclare,

I was able to reproduce the problem - my Terminal.app now behaves the same like
yours and a similar problem with a solution how to solve it can be found in the
Internet. There is a bug in Terminal.app (seems to be on my 10.4.9 system, too).
A description about what is going on is here:

Ok, sow how I could solve my problem: I double-clicked Terminal.app (which 
automatically calls our exec '.../octave' script that we have written) and then 
I called the 'system' command in Octave

   octave-3.0.0:1> system ("exec bash")

on that system command I type

   MyMac:~$ rm ~/Library/Preferences/com.apple.terminal.plist

to restore my Terminal.app's defaults and then I close Terminal.app via the main 
menu to make sure all windows are closed and no other running script is left in 
any of the windows. That's it, does it work for you, too?

And after that quest I will never press the 'Apply All' menu entry in the window 
menubar of Terminal.app anymore ;)
