Ok, this is again mainly a note for myself about my computer. The Show Desktop icon disappeared from my Quick Launch toolbar a few days ago – a problem that I’ve had before, but I couldn’t remember what I did last time to fix it. Google turned up a solution here. All that is required is to create a text file, named “Show Desktop.scf” containing the following:
[Shell]
Command=2
IconFile=explorer.exe,3
[Taskbar]
Command=ToggleDesktop
and then copy the file to C:\Documents and Settings\Username\Application Data\Microsoft\Internet Explorer\Quick Launch, which can be done by just dragging the file icon onto the Quick Launch toolbar.
