All of my icons have disappeared off the desktop of my iMac G5, i cannot open any applications except for safari. When a webpage pulls up, i get a "shockwave flash plug in failed" and it shows a square with a question mark on certain images. I have tried to install the shockwave flash plug-in again, but it will not open the download. I can see all of the applications when I click on the apple and get the drop downs but they are all greyed out. Anyone have any suggestions?
