File Maker Pro 8 and Mac OS X 10.6.4 - can't modify
I've just upgraded to Mac OS X 10.6.4. When I open the database I can't modify it. It comes up with an error messge - 'This Action cannot be performed becasue this file is not modifiable'. When I open it on the old computer that is running Max OS X 10.5 it opens and works fine.
Advice? Does 10.6.4 not support File Maker 8? Do I have to upgrade to 11?
