>Hi, I have Windows XP SP2 in my PC, and the last weeks the application icons disappears; the Microsoft Word, Excel, Visual FoxPro, etc., show a white square instead of application icon and the files asociated to them too. The application works, but the icon of the files (.doc, .xls, .ppt) appears as disasociated file.
