Expanding "screen size"

hello kirupa friends…
having a brain block here…

i want to create a document that expands on a rollover. the “static” screen size/document dimensions should be 88x31 and then when a user rolls over, that 88x31 expands to 120x240

please provide ideas to get my idea going. jog my memory. i’m an intermediate flash user and some what comfortable with AS1 and AS2. haven’t gotten into AS3 yet.

i cant just create a button b/c i need the static screensize to be 88x31. if i create a button, then the static screensize will have to be 120x240.

thank you for your help…
