just upgraded to fw4 yesterday morning. though a couple of things seemed odd(see below, #2 & #3) it worked fine for ~100 shots, then last night, out of the blue, it started acting up. tried to upgrade firmware again, used different cards & batteries but no luck. symptoms:
1. it doesn't record to memory card, i.e. i take the picture, the orange light stays lit (or before the second firmware upgrade try, it would light up green&orange intermittently - now it is a steady orange), if locks up the rear screen so that it stays on&shows whatever's in front of lens (i.e. as though i am composing to take a pic, but it won't come out of this mode - play button is useless, any other button is useless). camera doesn't turn off until i remove battery. when i restart, no image is recorded onto the card.
2. since the first upgrade, all icons in q menu only show iso, i can't modify them(it was this way immediately after upgrade, but i was still able to take pictures for about 100 frames; it is still this way)?
3. on the right bottom of rear screen, right above iso gauge, there is a darker, semi-translucent rectangle that is blank - it looks as though an indicator should be there but isn't (this also has been this way since first upgrade attempt, but it was working until last night). i put a shot of the back screen with this in the link below, as well as in the attachment to this post:
anyone else have this issue? any pointers as to what could be wrong would be much appreciated. thanks!
