Flash movies flash when they come on

[Guest]

I have been bringing some flash movies into a Powerpoint show, both full
screen and partial screen. When I play the show, the screen flashes for a
second before the flash movie plays. The color that flashes is whatever is
defined as the background color in the movie properties. If there's a
transition to the slide, the transition plays with this color and then the
flash movie comes on. Once I have played the show, it usually starts working
right, so I thought maybe running it as a pps would work, but it didn't. I
have tried a lot of things, including combinations of the scale and window
options in properties, playing it on a laptop, playing at different
resolutions, inserting the flash movie manually or using an add-in (I have
PowerPlugs FlashReady), creating the flash movie in Player 8 or 9 format.

I'm really puzzled because I can't find anything about this on the internet,
yet it's happening to me very consistently, and I'm about to give up on using
Flash.

Any help would be great.

Thanks

After a few more tests, I think it's possible that this is fixed if I export
the movie as Flash 7. Does this give anyone an idea what's going on? I have
the Flash 9 player installed, am running Flash CS3 professional and
Powerpoint 2003 SP3.

Movies in Flash 7 do work, so I'm guessing it's incompatibility between Flash
9 movies and Powerpoint 2003. If this makes sense, is there any fix other
than buying that latest Powerpoint?
