Since this is the closest thread to the problem I just had for the first time on my phone too (Droid 1) it is probably more wide spread. I was thinking about a shot I took last night and went to hit the gallery and noticed it wasn't there....so I thumbed through the five screens I have and well---couldn't find it. Okay---something I did took them off. I went to put them all back on and then while I was about to let go of the screen I caught a glimpse of the icons on the screen. The icons flashed on the screen and off. I did a double blink like I had just saw a ghost and let the icon go. As soon as I did, tada. They were back.......so, it's likely a broader issue, and was my first time in seeing anything like it. Just mentioning it.
