Expaning tooltip

Hi all,

I’ve made a map of Europe with a tooltip on some of the countries. When you hover over lets say Spain, you get a tooltip saying ‘Lets go to Spain!’.

Now my problem is that sometimes the tooltip is to short for the text.
Is there a way to make my tooltip expand according to the text I want to show?

Actionscript on frame 1:

function tooltip (string) { 
 xmouse = getProperty("", _xmouse);
 ymouse = getProperty("", _ymouse);
 duplicateMovieClip ("_root.tooltip", "tooltip1", 1);
 tooltip1.tooltip = string;
 setProperty (tooltip1, _x, xmouse);
 setProperty (tooltip1, _y, ymouse);
 startDrag ("_root.tooltip1");
 tooltip1.gotoAndStop(2);
} 
function remove_tooltip () { 
 stopDrag ();
 removeMovieClip ("tooltip1");
}

Actionscript on the buttons/countries:

on (rollOver) { 
 _root.tooltip("Lets go to Spain!");
} 
on (rollOut, dragOut) { 
 _root.remove_tooltip();
}
