Who wants a crack at forensics?
WTF is this? Turned up when I started shooting flats sat evening.
Restarted the laptop, camera & program several times but it wouldn't go away.
Finally in desperation, I removed the camera from the 'scope, removed all leads, re-connected everything, restarted everything and bingo - happy days, no more stripes.
Camera was cooling down during this, could that affect the flat like this?
weird...
