I noticed some time ago that, when I bought something on ebay and pd thru PP, it appeared there was no logout from the ebay/PP transaction. I went into PP and was still logged in. So I've started going to PP right after I do the ebay transaction and log out. I didn't know it was supposed to time out and would be afraid to give it a chance to do so. I'd think ebay would set it up so that when the transaction was finished, you'd be automatically logged out of PP.
