For several versions now in Photoshop/Bridge, when you open photos in the Camera Raw browser/editor, and select several image from the film strip to "Merge to HDR", it opens up the HDR Merge Preview screen like normal, but if you use the Enter key to quickly select the defaulted "Merge..." button, it will then open the normal "Save" dialog but get stuck in a loop when you click on Save. It will go away and pop up again asking you to save repeatedly, sometimes crashing the program. I have to hit Save one time, then the next time it pops up hit Cancel in order for it to proceed like normal and take me back to the Camera Raw editor so I can edit the new HDR file.
