I am running Vista Ultimate on one machine and Vista Home Premium on another\nmachine. Something has happened to the Control Panel on the Ultimate\nmachine. When I bring up the Control Panel window in the "Control Panel\nHome" view the icon on the desktop is the correct icon (looks like a little\npanel display). However, when I select the "Classic View" a new window\nopens and the icon changes to a blank page with the upper right hand corner\nfolded over. If I close the "Classic View" window first and then the\n"Control Panel Home" window the icon returns to the good one. Also, in the\nStart Menu if the "Display as Link" option (Start Button>Properties>Start\nMenu>Customize>Control Panel) is selected for the Control Panel nothing\nhappens when I click on the Control Panel (button?) in the Start Menu. If\nthe "Display as Menu" option is selected for the Control Panel the list of\nControl Panel stuff appears as a menu when I click on Control Panel in the\nStart Menu - as it should. Neither of these problems are show stoppers but\nsomewhere a long the line I have done something to screw up the registry??\nCan anyone give me a hint what to do, who to contact, or where to look in\nthe registry to attempt to fix these two (probably related) problems. This\nsystem has been running Vista since it first came out and I dread having to\nreinstall Vista and all the other stuff from scratch. I have asked for help\non this issue several times and several ways but so far have come up empty.\nHelp is needed.
