I have a bad habit of over-tightening screws!  If you ever do this and/or
strip the slots in a screw, loosen all the other screws as above (hopefully
you don't have more than one!) and then slightly rotate the panel itself
counter-clockwise.  In every case where I've had a screw stuck that I
couldn't start with a screwdriver, this loosened it enough to allow removal. 
I'm trying to be especially careful now but I like to snug my screws for RF
purposes (especially the one by the handle toward the front panel).  Since
I've now built 3 units I have a supply of spare countersunk case screws that
seem especially prone to "camming-out" by a heavy hand so I always replace
the stripped screws.

73,  Bill
