Adobe found a bug introduced when late changes were made to the Raw processing engine to improve rendition of M9 files. The current fix for LR2.6 users is to download and use LR2.6.1. The only change is the elimination of that bug and it is only relevant for M9 users. The problem does not occur with the LR3 beta (which also has significantly better rendition, noise reduction and sharpening powers). I have recently done a complete new clean install on a new sytem (64 bit, Yeah!) and am only just catching up. I have found that the bug exists in Adobe Camera Raw 5.6 as well, however there is no ACR5.6.1 available currently. Adobe has acknowledged the issue with both LR and ACR and reports that a fix will be available shortly. In the meantime I need to stay out of Adobe Camera Raw with M9 files and as a minor issue, trying to edit a DNG in Photoshop (from LR) reports the mismatch in versions as well, once you install the LR2.6.1 although the cure is not yet here. I don't have the LR2.6RC (release candidate) any longer. It did not exhibit the crashing behaviour but I don't know if version matching was an issue there. Personally I am looking forward to the release of LR3 and I hope a cheap upgrade. Mant M9 owners tht already own LR are waiting to find out if they will be able to use their entitlement to download LR to receive LR3. We shall see. Incidentally, the X1 already has a standard profile (usable in both applications of course) although the S2 does not. Neither X1 DNG files nor those from the S2 provoke the bug.
