Got a strange one that just started happening. Windows 7, x64, lightroom 2.6. I am trying to export a photo and when I go to the export pulldown, it just freezes up. I can do an export as previous, but that doesn't help. The CPU is not running higher than 5%, RAM is good, using only 1gb of 4gb available, and I can do everything else in lightroom with no issues. I did a re-install and that did not help. The only thing different from the last time I exported was my wife added photos with a new Lumix ZR-1.
