Victoria -- thank you for your suggetions. Unfortunately, still no luck. I am no OSX expert, but "permissions" are something that are repaired using Disk Utility (they are often garbled, and running the Disk Utility program in OSX fixes permission problems). I ran Disk Utility on the drives in question (network drives connected by lan cable through a second machine running the same version of OSX, a mid-2011 MINI). There were no permission problems noted, but at least the program would have corrected ones that were found.
If by "permissions" you mean Sharing access, controlled by "Sharing" in Sytem Preferences, then I have read/write authority on BOTH the drive and the folder where the photos are stored. I am still getting the "they could not be read" error message in LR 4.4. I installed Mountain Lion BEFORE LR 4.4 was downloaded, and 4.3 did not give me these errors.
If Adobe DOES have a fix, involving OSX settings, a step-by-step set of instructions, with screen shots would make life easier.
I will say I have been to this movie before, as we say, and it's NOT a good sign. Perhaps I should revert to 4.3 somehow until Adobe sorts this out.
Again, thank you for your prompt suggestions, but your suggested fix didn't work. Also, I am at a loss to find the "cog icon" to which you refer in the Sharing dialog, and in Finder, there IS a cog icon, but "Apply to Enclosed Items" does not appear in the drop down menu.
If I come up with something, I will post the information.
Steve
