Toni - Hang in there. Like you mentioned they are replaceable, it just bites that you might have to. Forgive my ignorance, but what is a CoL?
Alan - Climate really may play a part. Last summer was idyllic around here, the kind of summers I remembered as a kid. Comfortable temps and moderate everything. This summer was more the norm, 2 weeks after the last frost we were in the steady mid 80s, humid and very wet. Three weeks after the last frost we hit 90 degrees, The *Queen* just may not be up to dealing with such radical differences. If not I've found a few others that would be more than willing to take her place! *grin*
