Due to problems with booting W2K, and sometimes Avast or Kerio not loading properly, I installed the StartupDelayer from 2r studios (StartDelay1.10). I made the mistake of uninstalling it while it was set to delay Avast.

After that, there was no icon in the taskbar anymore, although it could be started by doubleclick on AshDisp.exe in Avast\Data.

I checked your Registry file mendioned earlier in this thread. I could verify that this registry item was already there, so I did not reload it by your string.

All else searching was in vain, I could not determine any wrong settings, comparing two almost identical systems.

Just before uninstalling Avast and then reinstalling it, loosing all the settings by that, I just tried loading your string, knowing it would not change anything, as my registry was identical.

WOW the registry still looks the same, but the system is working perfectly now, what can you say!

Thank you very much for your most valueable help, Thanks a lot.
