I have also noticed the icon missing in rare cases. For my situation, most my laptops have two (2) admin accounts. Once in awhile, the main admin account will have Task Tray Icons missing, including the McAfee one. As a computer specalist I am very confused why? However, if I log out and go to the other admin account on the laptop, all icons show without any problems at all. Yes, as they say, "I think the barn has al leak somewhere".
Anyone know what the process name is that makes sure this McAfee Task Icon gets run and displayed? This could indeed be a system register problem and there may be a simple solution to it, but I have yet to find it.
I also notice this on windows 7..
not sure why and how this happen..
sometimes it's gone.. comes back after reboot..
sometimes it's dissapear and we have to reinstall the pakage..
I find this often too. Again a reboot tends to resolve the issue. The other issue can be that the agent icon dosen't display when connecting to a client using TS when the client is on Win2003.
