When I clean the browser cache, cookies are also cleaned (according the warning text in the dialog box)
I restarted doogiePIM after the cleaning and started the browser.
I revisit a site where I had logged in during the previous session and the login was still active.
I can assume that the cookie was not cleaned.
This is not such a big deal for me, I can logout before closing the browser, but I hope you don't mind my nagging about (possible) bugs. Trying to make a very small contribution in making doogiePIM better :)
Thanks for doogiePIM (again) and your support
