Good morning.
I am using a MacBook Pro (early 2008) with OS 10.8.2 and Logos 4.6 SR-2 (4.60.0.3010).
I opened my library to tag new resources and found a number of resources that lost the tags I had assigned. There does not seem to be any rhyme or reason in terms of resource or the tag I had assigned. When I checked my library on my PC desktop the resources retained their tags.
Your help is appreciated!
