On double click disappears???

[alokwww]

I'm working on a site for a friend... when i double click one of the links on the top bar, the site goes black except for the bar and then when i click it again it comes back. the links to the files are below, go to the html file and double click a link and youll see what i mean. also, if you click the butterfly in the corner it starts to flap and it shouldnt do that. how can i stop it?

the files are:

http://www.geocities.com/a1okw/BSM/new/2.html

http://www.geocities.com/a1okw/BSM/new/2.fla

http://www.geocities.com/a1okw/BSM/new/2.swf

if you look at it, can you give me any other suggestions/tips on making the site better??

thanks
