I think this is normal... both my Vista laptops do this (though both are sony)
Doubt it is a sony app though as mine are all clean installs and never use Sony recovery - having said that, I do install various sony tools
But the bottom line is, even with just vista installed and nothing else- not even the relevant extra drivers and sony apps, it still does the flash
I assume it is something to do with the graphics card being initiated or something - who knows but Vista does like to flash a lot.
For instance, when asking for permission on various Admin things, it does not only bring up the error message but it feels it needs to flash too
This to me sounds graphics because the flash seems to be needed in order to dim the background but not the error box
