Help regarding Hover Caption Tutorial on Kirupa

Dear all .
My query is in respect to the tutorial posted on kirupa :
[URL=“http://www.kirupa.com/developer/mx2004/hover_captions.htm”]http://www.kirupa.com/developer/mx2004/hover_captions.htm

Now :

  1. If I want to add a line of caption ,the moviclip expands in a horizontal manner. So , if I write a big description , the caption movieclip occupies whole stage width .
    How can i make this movieclip exapand in a vertical fashion after a fixed no. of characters

  2. Suppose a button which is inside a movieclip has been applied this function , the button action doesnt work !!! only the hover caption appears . ( specifically the button on(release) action ) !!

What is the possible solution . ??
Any help wud be highly appreciated .

Regards
