lately and with no explanation half of the tray icons disappear every time I start up XP SP3. I use Process Explorer (procexp.exe) to look for the missing processes and they still there. When i kill and restart explorer.exe, the tray is complete again. I don't know how to diagnostic or repair the problem. Any suggestions? Thanks in advance.
Many times this can occur when you log into your user account before Windows XP has fully loaded all its start-up processes. I tend to wait for my hard drive light to stop blinking before I log in, and that has alleviated the issue for me.
