[Camino] eBay troubles

Hello,

I need your help :-)

When I attempt to leave feedback or ask a seller a question, I get bounced
to sign-in page . . . even though I'm signed in.  When I go ahead and sign
in, I just get bounced back to the sign in page.  Does not happen when I
use Firefox.

eBay told me to empty cache; that has not helped.

Can the problem be fixed . . . (I really like using Camino)?

Jane
