I upgraded to PSCS4 about five weeks ago, and finally got around to working with the ACR 5.6 adjustment brush and gradient tool. I immediately began to get 'bridge out of memory' warnings on any folder where I had used these tools on my .dng files. I see some discussion of a "memory leak" associated with these tools.
Is this a known problem, and is there a solution in the works?
