Ok... Problem solved
I think Fred you were on to something
... If you shine a bright enough light into a sensor for long enough, it is bound to be affected in some way. What I was doing, shining a CFL into the sensor for 5 seconds is an extreme thing to do in regards to light exposure. Is it any wonder the sensor was collecting light when it wasn't supposed to be
Under normal circumstances, you won't experience these sorts of conditions.
I left the camera in a semi dark spot with the sensor exposed for 5 minutes. Then covered the sensor, took a 2 second dark, no problems.
Even a 2 minute light sub right next to the computer monitor I am using right now didn't really show up that much.
So the bottom line here is, I have to be really careful that the fluro in the kitchen remains off when imaging, and, I worry too much...
Cheers everyone.
