Hi!
It seems like something is weird regarding SOLO buttons... Sonar behaves strangely when I'm clicking the SOLO buttons on the TV, CV, Inspector and even the solo buttons on Plugins GUI!
Example:
When first soloing a track in "view #1" and then un-soloing it in "view #2" (for me it is the plugin window) sometimes the "other tracks" are not going back to an "audible" state. Sometimes, there is even complete silence during playback. Seems to impact instrument tracks for me so far, but since I am rarely using those (I'm an independent Audio / Midi tracks kind of guy) I am pretty sure that I could reproduce this with other track types... I'll try again soon.
Anybody else noticed something like this?
