What have u done to the Photoshop plugin?? It does not allow pan with middle button anymore! Every time the same old story: 'it's not us in Adobe' and Adobe saying 'it's not us in Logitech'. I remember when you had the most solid app for mice, now it's just hit and miss. People are doing their jobs with these things and you don't seem to care, just fiddle around without enough testing before. real shame!
