On behalf of Tony, I think what he referred to was the sliding glass patio door. I guess we DO all share a common language....maybe:-)! Having a number of friends here in British Columbia who are from "down under" Oz & Kiwi, Australia & New Zealand, they do have their own way of referring to different things. Sorta like the first time I went into a hamburger joint in Shamrock, Texas. I couldn't understand the gal behind the counter, and she couldn't understand me! I soon learned to drawl just like y'all! Except "out & about":-)!! Right, Merkins? cheers, old Doug
