"Plugin tool script error in method ik_isIKContainer"

Hi! Without any reason, Flash CS4 starts displaying this message over and over again in the Output window, stealing focus from anything else I’m doing. (I hate hate HATE stolen focus. Bad UI designer!)

Googling doesn’t seem to help. I find lots of sorta-similar things, some recommend using or not using “Menu - Control - [FONT=&quot]Enable live preview” but that’s checked ‘on’ and greyed out for me. No idea what relevance that has for what I’m doing (mostly as3 scripting, my art is loaded via URLRequest)[/FONT]

  • I’m NOT using IK bones in my file

  • When it starts happening, it happens in ANY file I open, even ones that weren’t reporting this error earlier

  • Rebooting helps, but loading a recent file makes the error pop up again

  • Using CS4 version 10.0

  • Windows Vista

Thanks in advance for any suggestions you may have!
