Camera RAW scrolling with no commands? No more Shift + select multiple frames?

Hi , long time ACR user but today the edit frames are scrolling left with no command?

and it wil not let me click + shift - select multiple frames - I must have hit some wrong keys or my mouse is doing it?

I tried default settings and restarting pS and removing the battery from the mouse but nothing has worked so far?

Your help, reflections and dissertations appreciated.

Thank You

Rodger
