I can't open files from Photoshop, and I also can't save files to a specific folder from Photoshop and Lightroom. I have to select whichever folder appears first otherwise once I try to change the folder the dialog box closes on me. How do I fix this annoying and very frustrating problem ???
We can't know. You have not offered any system information or otehr technical details. Generalyl this is unrelated to the app itself but comes down to issues with your file system like certain permissions on folders being crooked and the program not being able to access those directories or just as well external processes like virus scanners blocking access.
