Don’t upgrade Lightroom to 1.4

Damn ye, Adobe. There be bugs in that 1.4 update that you rolled out.

For other folks who use a pc and like to convert to .dng while importing, this update is no good.

I too am getting the "an unknown error has occured" when trying to view my files at 1:1 size. Solution (so far) has been to downgrade to the 1.3.1 release, available here:
