I have a problem that sometimes some apps don't show on system tray but sometimes they do show. They don't appear on system tray but they are running if seen from task bar.
What is wrong?
Looking for your helpful answers.
OS: Windows XP
Edit: Some apps include nimbuzz, download accelerator plus, etc. The Windows is working perfectly well, i have also up-to-date anti-virus installed so nothing wrong with Windows.
