Okay, but now there is a new problem: after replacing the < with the entity, the code can't be edited anymore. (And if I want to assign the shared action to e.g. a button Captivate crashes completely.) Just when I delete all < or > I can edit the code and at the end I have to replace the < all over again.
It seems to be a bug in the programm. Is there a way to report that to Adobe?
