Right Morgan.... can't get to the catch under the cover with the lid closed!

And doc, I have TRIED and TRIED - I am at a brick wall here!

It's REALLY bugging me - only thing I can think is a pen fell outta my folder and is laying somewhere that the lid cant' close all the way and maybe this is putting pressure on the latch so it won't/can't open. Will still try a few more times, but I WISH I could get the top's cover to open so I can work my hand down in there !!!!!!

EDIT Tried the tag light thing... got the lens/bulb out but could not see how to remove the socket assembly.... will try at that again.
