2 Flash Questions

ok,

basically im tired of iframes and scrolling divs etc.. so i am going to display my content in flash. however, to do this i need answers to the following questions:

1) how can i get a normal html link to get a flash movie to change scene?
2) how can i get the text i use to be selectable?
3) can flash movies have transparent backgrounds?

Cheers!

1)easy, this page http://www.rolandschaer.ch/blog/archives/000018.php
has a good explanation/example
2) set as selectable in the properties dialog within the flash ide - or with actionscript like
myTextField.selectable=true;
3) yes they can, the transparency is governed by a param set in the embedding html - it isnt supported by all browsers though (netscape/moz if i remember right) so its pretty pointless, heres the code anyway
<param name="wmode" value="transparent" />
