This might be the final nail in the coffin. LR wants to scan my folders for stuff to import! Without my permission! So, because I have some folders with a lot of images in in those places that I don't want in my LR catalog, it's taking ages for LR to be available to import from the specific places that I want to point it at. Did the geniuses that conceived this idea have the good sense to allow you to choose for this behaviour not to be the default? I can't find any options for the import dialog. Any help on this would be very very much appreciated. In the meantime I'm going back to Capture One Pro (Hopefully Phase One managed to fix all their crappy network workflow issues since I last used it).
Calm down. You can specify which folder will be imported in all versions of Lightroom.
On the left hand side, the folders you want to import from can be selected.
Incorrect answer @dj_paige, sorry. I can't do anything whilst its scanning my "common" folders. Massive mistake. (Like the new interface though.)
It'd be really really useful if Adobe updated their help documents when they're making mahoosive changes to stuff too.
