Updated GS to v3.12. The first time I use 3.12 rewired to Sonar 3.1.1PE, it's acting flakey - missing notes from the MIDI sequence I have triggering it. So, I go to remove it from the project. Close GS3. Delete the tracks from Sonar. Try to remove GS3 from Sonar's synth rack and get:

"Giga3 is currently open. You must close all ReWire panel applications before closing this project or removing a synth from the rack."

The dialog only has an OK button, so the synth stays in the rack.

Okay, GS3 is closed and there's nothing GS3 related showing in Task Manager. Hmm. I try to close the project. Same error message!

"Giga3 is currently open. You must close all ReWire panel applications before closing this project or removing a synth from the rack."

Again, the dialog only has an OK button, so I can't close the project, either! WTF?!

The only way I could exit Sonar is to kill its .exe in Task Manager. I rebooted and opened the project again (twice more, actually) with the same issues.

What's up? Anyone else encounter this? Anyone fix it?

Thanks in advance for any clues!
