Flash Cookies and Tor.

  Hello,

When I use Tor, I disable Flash.  However, when not using Tor, sometimes I 
do use Flash.

I was surprised today to discover in my .macromedia folder on Ubuntu dozens 
of flash cookies.

Can these cookies have connected my static non-Tor IP and the various Tor 
IPs. In other words, if when using Tor I go to www.yahoo.com 
<http://www.yahoo.com> can Yahoo know my "real" IP based on the flash 
cookie it sent me when I connected earlier when not using Tor?

And can the flash cookie connect to the website even when flash is turned 
off?  I assume not - but I don't know this.

Thanks.
