I'm not certain what else there is to say. For quite some time (last month or two), whenever I try to save a photo image as processed through ACR as a .jpg the image fails to show in Bridge (although the save shows.) To see the image I have to purge the cache in Bridge. I should say this only happens when saving a 16bit image at 300dpi. If I should change the said image to 72dpi for use in email the saved jpg image can be seen in Bridge. At the time I requested input on this I checked the preferences for Bridge and they seemed to be what is recommended.
This morning I took a couple photos and ran them through ACR at 300dpi. When I saved these as jpg full-frame images they appeared in Bridge and I didn't need to purge the cache. No idea. Perhaps there was an update that corrected the issue? If this reoccurs I'll mail back, and thanks for your input.
Cheers,
