Anybody encountered this issue, that the Adobe Bridge (CS3) is very slow in displaying the thumbnails, or when you click on preferences it quits. I did face this issue, so here is the solution.
Delete the system preference folder located Users/[Username]/Library/Caches/Adobe/Bridge CS3 and delete this folder.
Bottom line use bridge to manage your files and workflow, this is one software which makes your life much easier. ( I'm not promoting this product, but it helps your workflow better)
