NAVIGATION GLITCH

Question

Can anyone enlighten me as to why this glitch is happening on
a website I designed?
Please go to

Why does the "Welcome" page continually pop up during page
transitions on button release?? In some browsers it pops up for an
instant, others as long as 30 seconds before opening the next page
which will cause my audience to abandon the site.
It seems as if each new page takes long to load so during the
interim my "welcome" page fills in the blank. Each page is an
external .SWF which I thought was the most efficient way to build a
Flash site thereby avoiding long pre-load times. The largest size
of any .SWF is 280KB. That doesn't seem too large to load in an
instant. I'm using the first version of FlashMX. Any
advice??

Answer 1

The first page has an "ENTER" button which links to a "HOME"
page which has six additional buttons linking to various other
pages. All of the pages are external .SWF's. The code route for all
buttons is BROWSER/NETWORK>LOAD MOVIE which prompts me to enter
URL and level:
on (release) {
loadMovieNum("blvdProp_home2.swf", 1);
I use level 1 for each .SWF so it automatically bumps the
previous page out. All of this works except that the initial
"ENTER" page reappears for 1 to 5 seconds during the transition
from one page to another upon release of a button. Here's the site
