I personally think that PopTray is a very good utility. I was using a little software called eRemover 2.4 by Victor Javier (1998, only 30K, no install needed but it uses to save info into registry) and it was simple and nice.
Now I found PopTray and I think it's a very good software, also because it's freeware!

But, I think I have found a bug: I'm using the Password Protect from Advanced Options. It works fine but, once I quit PopTray and I run it again, PopTray doesn't ask me the password, giving free access to ALL options, messages, etc until I clic To Tray button.
But, the problem appears every time I run again PopTray.
Please fix the problem.
