I'm curious.  I have the same setup (64bit F10), and I don't see the 
same problem.

If I unlock my key, I can ssh to hosts where it is installed without any 
prompts, as expected.  If I do "ssh-add -D", it prints "All identities 
removed".  Afterward, I'm prompted for my ssh key passphrase.  If I 
cancel the dialog, ssh will ask for my password.

I can imagine a couple of things that might cause the problem that 
you're seeing, if you have time to do a couple of tests.  First, do 
"ssh-add -D" and then "ssh-add -l".  Send the output of the latter 
command.  Also, the output of "set | grep SSH".  Then ssh to a host 
where your key is installed with "ssh -v" and include the output of that 
command as well.  Hopefully one of those three commands will illuminate 
what's going on.

Thanks, Wolfgang.
