After I've added a link to some static text via the Text Properties panel in Flash CS4, if I click the field again, the URL I'd entered disappears! This is quite annoying if I need to update my link or simply just copy the URL in there to use somewhere else. It has been inconsistent too, and I can't find the reason. Sometimes, holding down the Alt-key on PC will let me click in the field and keep my text there, but not always. Is this a bug in Flash, or is there some kind of trick here?
