Lightroom 4 help!
I have a mediocre server connection at my office (long story), and every once and a while I'll just get a blank stare from various different applications when I try to save a file. With the lousy connection, the network will sometimes report that the destination disk is full even though there are several terabytes free. The software knows about the terabytes of space, but can't access it because of the disk full message, and the software just hangs.
Now my first check for a blank software stare is "is there adequate disk space" and "are there adequate permissions (including connection at my office - not an issue for you) to access that space"? I only bring this up because I once read about some permissions issues with older LR versions on Macs.
