Well, acemike, I guess you learned a thing or two in your 25 years!! Exactly as described. I couldn't believe how far the one screw had backed out. I actually thought that it was stripped but everything tightend up just fine. Maaanny thanks for that tip. Imagine, 13 years of turning that lockset at least twice per day and I never notice the disappearing windows. Make ya feel a bit nonobservant!
Oh yea, thanks for the welcome, Square Eye (sounds like a date I had in college many years ago - *shudders*).
