iPod touch problem with dim icons on touch

anyone experienced just one icon on your touch being dimmer than all the rest, its very noticable.

i rememeber seeing it once on calender.

.... and then after i exited Installer i saw it on that.

im wondering whether its normal llike u kno if uve still got an app running in the backgroun this is why it does this i dont kno, im worried lol.

it dissapears tho when you press home, or press sleep/wake, as tho it has been refreshed.


please i would appreciate some feedback from you peeps if u experienced the same thing
