PS CC crashes keyboard

Question

A new one on me--After using PS CC for some minutes the entire keyboard hangs. I am still able to use pointing devices and the enter key, but every other key stops functioning. Interestingly, my keyboard is illuminated, and has a few second inactivity delay, after which the backlight fades. When the keyboard crashes, the keyboard stays illuminated. If I try to use the keyboard with other programs, it is also non-functional until I close PS. Then normal keyboard functioning is restored.
I googled this and found that another person reported the same phenomenon, using a Mac. I am on a PC running Win 7 Pro. Does anyone have any clue as to what might be causing this? I obviously can't be restarting PS every five minutes, especially given that once this happens, saving any open files is impossible.
TIA,
Toby

Hi Chris,
None that I know of. To be fair this behavior has only begun to occur; I used PS CC regularly without problem. The only thing that I can think of is that I recently installed CC 2014, which caused some complexities using Bridge, which has changed my workflow slightly. Bridge CC is a bit confused as to where its loyalties lie. I used to open in ACR and then open from there into PSCC. That no longer works, as it apparently tries to launch into CC 2014 even if CC is open. "Open in" in the context menu does not contain an option for CC, so what I have to do is to launch CC, then go to Bridge and choose simply "Open", which launches an instance of ACR that connects to CC when I choose "Open".
Perhaps this causes some state in the system that, combined by some as yet unidentified keyboard command, causes the keyboard driver to hang. Just a completely uneducated speculation. Using CC 2014 I use my normal workflow faultlessly, so I will just go ahead and get all my plugs installed and drop CC completely.
