Bridge is very slow but not all the time. It also has a nasty habit of crashing my whole system on the iMac I use for editing. The main issue is that once I have opened the image on PS and edited it, once I go back Bridge is extremely slow again. Sometimes I have to wait several minutes to look at the photos again to see which ones I want to edit. Never had this issue with previous versions. I have reduced the amount of photos in the folder I am looking at and also used a different hard drive to extract the photos, all to no avail.
