You prolly already know this crap, but for those who don't...
I recommend making a copy of your graphics folder before doing anything, in case something goes whack.
Go into:
C:\Program Files\Full Tilt Poker\Graphics\Table\Elements
And rename TableRT to something else, I made mine TableRT1
You have to rename so it isn't found by FT.
Then exchange the Cards file with this one:
(rename to Cards after saving)
Then go into:
C:\Program Files\Full Tilt Poker\Graphics\Table\RaceTrack\Red Carpet
(or whichever color you are using)
Then exchange the Table file with this one:
(rename to Table after saving)
Then go into:
C:\Program Files\Full Tilt Poker\Graphics\Table\Avatars
Rename SeatRT_On to something else, I made mine SeatRT_On1
Then make a copy of SeatRT_Off and rename it SeatRT_On
This will eliminate the active player's box from changing from blue to white.
Some multi tablers may not want to change this mod. I did because the colored lights under the player's name when they are active is good enough for me.
