The A02 ROM update did NOT fix this issue. I see in another thread that apparently a Toshiba e830 owner is also experiencing this same problem with his unit after upgrading to WM2003SE so my guess is that this is a microsoft problem and not a dell hardware problem.
My main frustration with the x50v is that even when the CF card does work (which is usally), it is PAINFULLY slow. Can't play any .wmv files (video) in WMP10 (it errors - copy to BIS and works fine...) and even regular .wma music files routinely skip when playing from the CF slot. I've tried this with two different CF cards from different manufacturers. One is a 4GB Lexar 80x card so its not the card that is the slouch... VERY frustrating.
I just wish Dell and/or Microsoftw would come out and acknowledge this commonly encountered problem by so many of us rather than allowing us to continue to waste time bantering like this in forums...
