Things are really buggy in Zoho -fine this morning, unusable this evening

Several hours ago I was using Zoho, it was fine. Now it's so buggy. Has something changed? Javascript, CSS something like that? I'm using Firefox, same as I always use, it was fine this morning. Now this evening it's buggy all over.

All through the interface the content of window runs off the screen, but scroll bars do not appear. I have to resize my browser window, and keep changing the size then suddenly the scrollbars appear.

Mail, I click on a subject and the body of the email usually appears below the list of emails. Now that no longer happens. I have tried to open them in preview mode, that does not work either.

Notebook: click the button to Add RSS and the dialog box that pops up is mostly below the bottom of my browser window so I cannot see or use it. This same behavior appears on other applications and functions.

This is terrible, I was just looking at upgrade options, thinking that Zoho was the application I wanted to use, and would be better than Google apps or anything else I had found. Now it's rendered useless.

Please help!
