Plasma question

[aimforsilence]

So I’ve had a Panasonic G25 THX certified plasma for almost a year now. I've obviously used it for more than 200 hours. But I’m still finding that I’m getting screen retention all the time. I have the Disney WoW disc with the pixel flipper tool, and run it twice a month for an hour a time. It seems to clean most of it up. But I guess my real issue here is why is it always retaining images. It retains my Telus optik tv box menus (i never have the menu on screen for longer than 30 seconds), it retains video game huds, it retains full screen letter boxes... it seems like anything that’s on the screen for longer than 10 seconds it retains a bit of that image. Quite honestly it's driving me insane, I find it inconvenient to have to run the pixel flipper as much as I do. its a waist of time I could be using to watch a movie. So my question is this, is there something I can do to fix this issue?
