Excel now "read only"
I've been working on a large Excel file (Office 2008) on my MacBook (core 2 duo/Snow Leopard) and recently got an iMac with Lion. I transferred everything from the MacBook to the iMac via Time Machine. Now when I open the file on the iMac it comes up as "Read Only".
I've checked the permissions and it was still "read/write" for me; I tried giving "read/write" to everyone and it still opens as "Read Only".
Any thoughts?
