Hi Mike,
Sorry for the late response.
What URL does your bookmark link to? If it links to
http://artsoftcontrols.com/[yada yada yada] then that's probably the reason why. If it links to
http://www.artsoftcontrols.com/[yada yada yada] then that's probably not it. It may not be a bad idea to just re-bookmark it... =)
(I had a similar issue - homepage was set to artsoftcontrols without the www, so i showed as being not logged in every time i opened Firefox... but, every time i clicked on anything I was suddenly logged in... i fixed some links that were malformed elsewhere in the site, redid my homepage, all is now good...
)
Thanks,
scott
