Thanks for the background feedback. It doesn't flicker when reloading with my browser or Internet connection but I know there can be a 'white flash' issue with some combinations. I have to figure out how to edit the script so the background doesn't reload. On it!
Curiously, my post has vanished from the forum. I checked the rules and there's nothing about posting a web link. In fact users are encouraged to search the web or other Toyota information sources. I don't know if the post was deleted for some reason or it's just a glitch. Odd.
