Hit any reply, and it may be 2 or 3 minutes before the composer opens, you can pop over to a different workspace screen, like to htop, and the system is not doing a thing. But just switching workspaces seems to generate enough of an IRQ storm that kmail finally gets to execute. Once the composer window is open. then everything is back to normal, till the next time you click one of the reply buttons. I rebooted last night, and the lag is now only 20 seconds or so, but something has definitely gone aglay in one of the updates recently.
