[Leica] Solved: Cold Weather M Focusing

[gcr910 at msn.com (Gregory Rubenstein)]

Charles Hehl nailed my cold weather focusing problem. Was shooting while 
wearing a pair of clever new mittens on which the upper half flips back to 
allow one's fingers to grasp things. The upper half of the mitten, when 
flipped back, apparently blocks the smaller viewing window in varying 
degrees (depending on hand position), causing the focusing/metering block to 
fade or vanish. Never happened to me before, hence never occurred to me 'til 
Charles' comments. Took out an M after reading his post, intentionally 
blocked the window, then moved the offending finger and, voila. Now know how 
Homer Simpson feels when he says, "Doh?"

Thank you, Charles.
