Yes, but that's not happening. I logged on with the same account on
two PCs. On the first, I click 'Edit in Word' and it opens in Read
Only. I close the file and immediately click 'Edit in Word' on the
second PC, and it opens in edit  mode. Both have the same version of
Word and problem is not specific to a document  or library. It seems
that I can only edit from one PC.
