Hello, Apologies if this has been asked before, but a search of this forum has not brought up an answer. My problem is this. I have set up three users in our studio running Lion. On each Mac there are two accounts - an admin account with full privileges (install software, change settings etc) and a user account with limited preferences. On the user account I want to set it so that PDFs automatically open up with Acrobat, not Preview. I select a PDF, do File/ Get Info, and change it to Open With Acrobat and select Change All... This works fine until the Mac is restarted and then Lion forgets this setting and reverts back to Open With Preview. The same happens with .doc and .docx files which I set to open in NeoOffice instead of TextEdit, but which revert back to TextEdit once restarted. Anybody else get this? It happens on all three of the Macs I've set up. Might it be because the user accounts do not have administrator privileges? Thanks in advance for any replies, John PS Sorry for typos in subject title!!
