Hi Lynne,
I tried all you advised and I 'think' it works. Not sure what I did, but for some reason it works. I think it's this suggestion
'If you allow users to login to your site via both
http://www.yoursite.com and just yoursite.com (which you do), then you MUST have your cookie domain (AdminCP > Settings > Options > Cookies and HTTP Header Options > Cookie Domain) set to ".yoursite.com" (no quotes, but note the period at the beginning) or your users will have problems. Also, make sure to tell your users to click the Remember Me button when they login.'
Either way, thank you for your help and the time spent. Cheers, Jay
