Gotoandlearn carousel / limit reaction area

hello
i’m tweaking the well known carousel from gotoandlearn v3 flash 8/as2 as a navigation.loading external mc’s onto stage.
i searched the forum but couldn’t find a post on my problem:

is there a way to restrict the carousel movement e.g. when the cursor moves a certain distance away from the carousel ?
it’s slightly disturbing when you load something onto stage and the carousel keeps moving

thx for reading

fla attached ( flash 8 )
