Different things opening Zoho from office and from home

Different things opening Zoho from office and from home

In the office, I use Windows XP and I open Zoho, and each utility separately. At home, I use Mac, and when I open zoho.com, signing with the same Google Account, I see a different window, with every utility in a left sidebar, and I cannot enter each utility separately, as I do here in the office where I work. Also, I cannot access to the same information: at the office I have written some text for testing Zoho utilities in Notebook, Wiki and Writer, but at home I cannot see these texts. Somebody can explain me what I am doing wrong? Maybe the Google Account is not fully implemented? Or maybe after clicking the first time with the Google button, I have to login in another way...

Thank you and BR,
Alberto
