When I open the dialog Send as email, and I want to replace the current address with an address from my Address Book, I click to get the dropdown menu and the spinning wheel starts. It takes 2 - 5 seconds for the menu to appear and scrolling in the menu starts the wheel again. Is it OSX or PM that is slow?
