long shot...
this may be a long shot but at least its a very benign fix, I have been reading on a different thread on how the Firewall may be affecting the performance of a particular app, try this: either register photoshop or Bridge under the Firewall listing of allowable connecting apps or turn off the Firewall to see if that is affecting Bridge and consequently Photoshop? or try -Allow all incoming connections- if the same then revert back to your original settings. I would also make a new account for testing and see if its the same behavior under that new account.
