After enabling separate process folders, explorer doesn't terminate?

Question

I have enabled the option called

Launch folders in a separate process

in folder Options but the second explorer.exe process does not terminate after all its windows are closed , so i have to manually terminate it before any other folder can be opened .

Any idea on how to solve this ?

I am using Windows Vista Home premium Sp2 .

You may have a rogue Explorer extension installed causing Explorer to hang. Sysinternals' Autoruns tool can show you any Explorer extensions; try disabling them and rebooting to see if the problem goes away.
