hello tim, thanks for your reply; I am not sure if you understood my problem and concern; I prefer to read pdfs in acrobat 4 in classic; its a great app. the question was how to make it the default on double clicking in the finder. With respect to pdfs that are not compatible with acrobat 4, open in colorsync and do a save as, you can then read it in acrobat 4. That's a great boon. That was discussed here not so long ago. To my thinking there is very little in versions of acrobat later than 4 that make sense other than to adobe's bottom line. write (via the print dialog and distiller), read, copy text, copy column, find text string, copy graphics, zoom (preserving original quality of vector graphics), edit text, annotate, move objects around on the page, copy object on one page, paste into another, sort pages in thumbnail view, drag page from one document to another, crop, project slideshows, make links that you can click on to bring up other documents or urls, underscore, circle, highlight. I am sure I have left out a bunch of other things you can do in it that just aren't occurring to me at the moment. Not bad for an app that dates from 1999. Capture (optical character recognition) is pretty flaky, I admit. What else would you like from your pdf app? -steve --- At Sat, 28 Jun 2008 05:51:29 -0400, Tim Collier <tim_collier at bellsouth.net> wrote: >Date: Sat, 28 Jun 2008 05:51:29 -0400 >From: Tim Collier <tim_collier at bellsouth.net> > >You do know that the latest version is Acrobat Reader 8, right? > >Tim > > >On 6/27/08 11:37 PM, "stephen e. schwartz" wrote: > >> After much trial and error I found an almost perfect solution to my >> problem, and in the process I understand system 10.4 a bit better than I >> did previously. >> >> Evidently system 10.4 will not allow a classic app to be the default app to >> open a file type (at least under some set of circumstances; I am not sure I >> wholly understand its ground rules.) >> >> But I found the following workaround: Select a pdf document, and in the >> file: get info window make the default app to open the document acrobat >> reader 7.
