Camera Raw 12.3 beware!

If you're used to using Adobe Bridge and ACR, to speed-up your work procedure, be aware that it's not just the interface that has changed—the speed and functionality seems to require a lot more system resources.  For instance, I'm one who uses the crop feature quite a bit.  When cropping large images, one can no longer just draw a cropping rectangle around the portion of the image you want—you must a watch the screen lag as you drag the corner handles from the edges of your full image to what you want.  Then, when you double-click— you'll get a blank screen—a bug that I've not seen anyone else complain about.  I'm guessing that Adobe is trying to make the experience more like cropping on other programs, but this is really agravating!  The new Geometry tab's anamorphic guideline control seems to be more limited in the amout one can manipulate the crop too.  —Yes—after a good amout of time, I finally figured out where that feature was hidden!  Really helpful for artists trying to crop photos of their artwork for documentation.
