Sign bug ?  - expansion pack

[Gryphon_Girl]

I used to know how to change signs, with the original editor, but how do you change them in the Expansion Pack and KEEP them changed ? If I type in the text I want on the sign EVERY sign (of the same size) in the mansion says the same thing. Am I completely missing something ?

If I have a small sign that says 'Keep Out' and I create another small sign that says 'Treasure Ahead', then both signs now read 'Treasure Ahead' and I have no 'Keep Out' sign.
Can anybody help me with this before I give up ?

thanks
