P: LR 4 Does not Import RAW+JPEG

Tried importing my Nikon D800 files into Lightroom 4.1RC yesterday. I shot Raw & jpeg. At first only the jpegs showed up in the import window, so I cancelled out of the window, ejected my card from the computer and then reinserted the card into my card reader. Went to import in Lightroom 4.1 and now both the jpegs and the raw showed up. I proceeded to import, but it took a long time, perhaps 15 minutes to import 40 images. Finally Lightroom 4.1 ejected my card and started to make previews. Three quarters of the way through the progress bar, it simply hung up. I was able to quit Lightroom without a force quit. Then I restarted and found all the previews had been rendered. Erratic behavior with import on Lightroom 4.1 on Mac 10.6.8. Never had this problem with Lightroom 3. Thanks, Larry

It's an instability issue during importation. No resolve today. (after the new 4.1 RC)
Not serious !!!

Having exactly the same issue with this when downloading from a Canon EOS 40D to a 2011 Macbook Pro with Mac OS X Lion 10.7.3, only bought Lightroom 4 today - such a disappointment!

When a card is inserted in my Card Reader and "importation window" automatically imports files (option checked in preferences), some RAW files are forgotten.
The card must contain imperatively RAW+JPEG files ( same issue ! None problem with LR1, 2 and 3)

Not happy, needs sorting

I am having same random problem

I am finding that it is semi random. I put my CF card into the reader and click import it will only show jpegs. If I hit cancel and hit import again, it will show the CR2 files just fine some times. Just repeating this a few times lets me import the files. This is new for LR4 and definitely seems like a bug.

Oh and I'm using Windows Vista with Service Pack 2. And have never owned a lightroom product before, this was a fresh install of the beta software.

I thought I would add I am having trouble downloading CR2 files from my EOS 60D while teathered as well. They don't even appear in LR4. I'm still using the beta which is set to expire on the 31st. I'd sure like this feature to work before I consider buying the software.

One thing of note though, is my videos do appear in the import screen (no preview is available though).

As it stands, I have to import my pictures from my Cannon EOS utility, then manually add the library to lightroom 4.

I've had it be pretty random as well. Import will only see the jpegs, quit and it may work. Some times it wont load a preview for some image. Nothing has changed for me except upgrading to LR4. If I load up LR3 and everything works as expected.
