Compose Mail bug on Opera

Compose Mail bug on Opera

I'm using the latest version of Opera and there seems to be a bug on the compose mail area of Zoho Mail. I attached a picture which I hope proves to be better than any description, but I'll describe it anyway. Instead of the normal appearance of the Compose Mail page (I've seen it on IE) , there is a white column under Attach|ZohoDocs|Google Docs.  I cannot type in this area, and I can only compose my e-mail under the [B][I][U] buttons. 

If I attach something, the interface changes back to normal with the full width text box, etc.

It's a minor issue, but it's a distracting issue on an otherwise perfect user interface. 

Am I the only one experiencing this?
