I just installed the Flux Bittersweet 3 64 bit plugin last night. I can load it into the FX Bin and the plugin appears, but immediately after I see it in the FX Bin, Sonar crashes. It seems like loading the GUI for the plugin is crashing Sonar. Has anybody else tried the new 64 bit Flux Bittersweet 3? 

Bump :)

It does, indeed, crash Sonar immediately.  Crashed Pro Tools, too.  Removing it from my system and sticking with Bittersweet II, haha.
