A colleague here at work recently brought me their laptop because they were having troubles logging into their local machine account. I was able to repair that problem, but noticed that a little mouse icon was being displayed to the right of the "Recent Items" menu item on the Start Menu. This is happening on all the accounts on the machine. I've identified the character's source as the font Wingdings, but I am baffled as to why it is being displayed instead of the traditional right-pointing arrow. Here is a screen shot of what I am talking about.
OS is Windows Vista Home Premium.
