I am running Vista
I had an internet explorer icon on the quick launch bar; it disappeared. What happened?
I booted my machine. The internet explorer icon was on the quick launch bar. I opened two browser sessions. I was reading information from these browser sessions. The computer went to sleep. Right away, I pressed on the power button to awake the computer. I looked at the quick launch bar, and the internet explorer icon was missing.
What happened? Why did the internet explorer icon disappear? I wasn't doing anything that I haven't done a thousand times.
