I recently up graded my Mac operating system from 10.4.9 to system 10.5.
Now when I try to open excel the message says that it is being used by me. It could be an issue with naming the computer. Everything worked before I installed the new system upgrade. It could be a software issue. I have three Mac computers. I have used one ID number on each computer for a total of three.
