Odd sleep/camera problem.

So, I have a weird problem with my BlackBerry Curve 8900. When I let my phone go to standby/sleep mode (I don't press the lock or standby buttons, I let it go to "sleep" after inactivity", I will click or roll the trackball to use my phone and the camera comes up. I have the camera assigned to the default right convenience key, but that's not the key I'm pressing.

This problem is hard to describe, I hope I did an accurate job of describing it. I've searched for this problem without any luck. Any help is greatly appreciated.

honestly, i dont know what "sleep after inactivity" is.

That's odd. I would look at your settings. Something may be a little off.
