I had a DAW project (Reaper) with a number of instruments in MIR Plug-In. I quit my DAW, but MIR stayed open, with most of the instruments gone but three remaining. This clearly should not be.
Now I've gone into the Win 8.1 System Tray to close MIR manually, and when I attempt to, it gives me this message:

ETA: When I subsequently restarted my computer, Win 8.1 indicated it was "configuring" some Windows Updates, which Windows had not mentioned to me until that point. In the past, Windows doing that has caused problems running Reason ( [url]https://www.propellerheads.se/forum/showthread.php?t=187515[/url] ), so maybe it is some Windows bug at work here too.
