Is the text event an Auto-start Event?
If so, then at the end of the event you need to put in "End Event"... unless you've already done that. In which case...
*SUMMONS BLUECUBE*
Haven't done that for a while. And I was bored, so what the hey!

The chest question I think is answered by way of preconditions and switches... but I always mess that up, soo...

Monsters who won't disppear. Is this as in:
Hero touches/talks to Monster. Battle begins. By killing monster they disappear?
If so, let me remember how... erm, switches and preconditions?
You'd need the "Monster Battle" event wit the custom defeat handler. In the victory part, have Switch [0001] or whatever turned on. Leave the defeat blank. Then the second page of the event would need to precondition of Switch [0001] ON, and be ENTIRELY BLANK - ie no picture, no events, nothing. And you might as well set that bit to action key.
If you need more detail, then I, or someone else, will go into it. I'm just a bit busy atm, so...
