Hello. I use Safari, and until today I had no difficulty opening .pdf files. Today I installed Adobe CS3, and when I try to open a .pdf file in Safari I get the following message: "AdobePDFViewer cannot find a compatible Adobe Acrobat or Adobe Reader to view this PDF. Please select one." The message is part of a selection box which is directing me to pick something from somewhere. Any hints? I don't want any change in Safari, just because I need to use PhotoShop. Where in Safari can I sort out this preference? I'm not interested in having an Adobe program view .pdf, I'm happy with letting Safari resume its normal functions. Anyone else have this trouble? And how did you fix it? Thanks in advance.
