Eric, In your comment you mentioned localToGlobal wasn't updating. Just in case: one misttep that I made when first working with AS3 was that localToGlobal no longer modifies the point you pass it. You have to evaluate the return value i.e.
changedPoint = someDisplayObject.localToGlobal(originalPoint); changedPoint not originalPoint. -jonathan On Wed, Jun 18, 2008 at 8:34 PM, eric e. dolecki <[EMAIL PROTECTED]> wrote: > Hey guys, > > Before I saw these response posts, I took a slightly different angle on > things.
