I selected 2 posts to quote. The first one by using the double quote icon, then the reply with quote icon. All worked as it should buy when I went to quote a different post quite a while later, the first post I quoted was there again.
I tracked down the first post of my double quote and the double quote icon was still checked. I had to manually uncheck it.
