Synchronizing Windows Vista Calendar w/Google Calendar

I've subscribed to my Google calendar with Windows Calendar and can read
everything ok, but cannot edit from within Windows Calendar because it tells
me it's read only. How do I change it to read and write?

Thanks,

I was wondering the same thing. I love and use Google Calendar. My one
complaint is the lack of offline access. This would solve that problem
