Zoho Mail does not work in Opera 11.10

Zoho Mail does not work in Opera 11.10

OK, so I have been using zoho for a month or two now. Initially it worked well using Opera 10.x.x.
I then upgraded to Opera 11.01, and I found that new emails were not being seen, and I was not
being notified of them, unless I refreshed the browser, or clicked on another folder, etc.

Now, today I upgrade to Opera 11.10 and the inbox frame on the right does not even show up!!.
And the left frame navigation that shows your folder, etc is incomplete. Under Folders, there is
nothing, and the minus sign is showing, which means it should be expanded as usual, but when
I try to click on it, I get nothing. See my attached screenshot.

I am using Ubuntu Linux 10.04 with Opera 11.10 Build 2092 for Linux x86_64, 2.6.32-30-generic.
In opera, you can right click in a frame and select 'Inspect Element'. This lets you look at the
source, check for errors, etc. Under the error console, I see the following for javascript.

https://zmail.zoho.com/mail/home.do?zburl=https://mail.zoho.com&istp=zb&reusewms=true&top=false
Uncaught exception: ReferenceError: Undefined variable: hidePreMenu

Uncaught exception: ReferenceError: Undefined variable: hidePreMenu

Error thrown at unknown location in <anonymous function>(event):
    /* no source available */

Also, I see one similar but for
Uncaught exception: ReferenceError: Undefined variable: shdrtree

Note that these are either onMouseOver or onClick type events.

I do not know if this has anything to do with it or not, but the only thing I have found.
I don't know if the problems are javascript or frame related or other.


Anyone else seen this, or have any help?
Or does anyone in Zoho Support have any help here?
The refresh issue in 11.04 has never been addressed or fixed for Opera, so who knows if this will either
but I wanted to report it. I like Zoho and want to continue to use it, but not if I have to keep switching to
another browser.
