Im running Windows Vista Home Premium an the other night the task bar started disapearing an then reappearing and sometimes i get the dialogue box which says "Windows Explorer has stopped working, check online then restart the program or restart the program".
Under the task bar properties the Lock the task is checked and the autohide taskbar is left unchecked, so i know its not that.
I did notice that about the same time the taskbar 1st started disappearing my ESET anti-virus program quarentined these items.
