Mid input sound muted on tracks in Solo mode

[Cobus Prinsloo]

Hi, this is a new one for me. Out of the blue, when I solo a track, I cannot hear my MIDI keyboard. The MIDI works fine (as indicated on my Scarlett 4i4 interface), but there's no sound.

I'm not aware that I changed anything in Preferences. 

The only unusual thing is that Sonar crashed 2-3 times today unexpectedly.

OK, it doesn't look like there's a way to delete a thread, so here goes:
Problem solved. It seems that it was a Windows issue - after I restarted, Sonar was back to normal again.

I have occasionally had MIDI I/O stop working after a crash because the driver is left in a bad state and the interface needs to be reset by power-cycling.
