When i click on internet links to pdf files/displays, my screen comes out black, with no print graphiccs, etc. Is this a preferences thing or a software thing? I have Adobe reader on my pro, but it doesn't seem to help the cause.
Adobe Reader plug-ins probably are the cause.
Look in HD/Library/Internet Plug-ins/ & remove any for Adobe, then restart Safari.
You can use Finder - Go menu - Go to folder... & paste in the following to get there.
