Camera app launches after screen saver

Hi All, I have a Surface Pro 2 with win8.1 all up to date. I have the display set to turn off after 30-minutes and the screen saver (Bubbles / Mystic) set at 15 minutes with the Login screen required.

Most of the times when I come back and move the mouse or tap the keyboard, the camera app shows up before the login screen. I used to have to reboot as there was no way to shut down the camera app.

I disabled the camera (don't use it anyway) in the Device Manager and now when the camera app shows, it has a message "You need to install a camera" and then after about 30-seconds it closes and I get the login screen.

A few days back I decided on a fresh win install so used the msoft USB Media Recovery (or whatever it is) tool and it is still doing the same thing with the camera app before the login screen. Driving me nuts.

Is there some way I can remove the camera app? I am guessing it is the Metro-version as it is full screen and no visible way to shut it down.

Thanks

You are running your battery down using the screensaver. Just have it go to sleep. It may be something that is a task, that could be causing the camera to wake up, when you go to use it.

Oops, forgot to say that when it is plugged in and running on power as it is most days for 7-9 hours.
