Parallels Compressor starts automatically

Every time I resume my Windows XP machine from suspend mode, the Parallels Compressor automatically starts. I cancel it and it start again the next time. Any idea why?

 

you need to unmount it from menu: device - > cd - > disconnect

 

I don't have a CD mounted. It's the boot drive that Parallels Compressor wants to work on.

 

OK. Thanks Sly Cat. I now understand what you were trying to tell me.
