Images are lighter in C1

I don't remember noticing this over the last few months so I'm wondering if I've accidentally reset something but, now everything I'm seeing in C1-4 is significantly brighter than it is in any other browser (Photo Mechanic, Nikon View NX, Bridge in CS3). About 2/3 stop. I can see the histogram looks pertty much perfect but highlights are slightly blown out.
Any suggestions?

Thanks!

  Hi,
  
  you don't mention your gear but from the software list I suppose it's Nikon gear.
  
  My camera is the Sony A700 and I'm making a similar experience - yet burned out highlights are not in my book but a histogramm shifted to the right, yes. In other words, a significant amount of images needs a negative exposure compensation to get exposure right and this shifting occurs when the views are being calculated by the software at first opening the directory which contains the most recent shots.
  For some of the first seconds on screen images look well exposed but as creation of the views advances the views are getting brighter and with a flat / dull appearance.
  
  Besides requiring a negative exposure compensation, most of my ARW (full RAW, not cRAW) images need a significant amount of positive contrast and colour saturation enhancement to give them the look as I have them in my mind from the moment of shooting.
  
  The main question is how this interferes with overall IQ. In general negative exposure compensation (without effectively burned highlights) should improve IQ, or at least noise levels. But I have no data yet if this is really true is this special case with C1V401.
  
  No idea if this shifting to the right is happening only with some few RAW formats or with all of them. Well, at least with DNG files it's the opposite, as they appear darker when the view is being created - and they generally require a positive exposure compensation. I had to convert some cRAW shots taken with my A700 first to DNG since C1V401 showed some flaws when attempting to process cRAW files directly.
  
  I'd like to know:
  
  - what's the reason for this "shifting to the right";
  - if it does interfere with IQ, given that the shifting doesn't lead to really burned highlights;
  - if there's some tweaking in the software I haven't discovered yet to change the opening settings in a way that the software starts already with 1/3 to 2/3 negative compensation when this is the range of adjustment needed by most of the photos.
  
  Cheers,
  Michael Fritzen
