I just got my Samsung Digimax 4500 and was so happy with it but the opening for the AV port and USB port keeps popping open and will not stay closed. Is this just common with these models? Otherwise the cam is very easy to use I just don't want to take it back and get another one with the same problem. The usb/av port once opened has like a little plastic "spring" holding the cover on its not detachable. Any help would be great. Thanks a million My other camera never had the usb covered so this one is definitely a step up it's just brand new so a little annoying to not be able to close it.
