jeron,
good to know, I have run into a number and heard of many warped early fridge models but yours is the first grey but yours is also the rist I have heard that could actually fix the issue...I know of a bunch of ways people tried to address the Fridge issues but with the one I play on regularly, none of that stuff works completely...maybe its just this one has too many warps...if you have just one concave in the middle you can push it up evenly and get it to work but the one I play on has more than one problem so to fix one makes another a problem and so on
anyway, thanks for the info, I will add it to my history
