Problems with Opera

[agalvao]

Using:
SmartGWT 2.5
Opera 11.51

I have a deployed app that runs in FF, IE and Chrome.
When I try to run it in Opera, the contents are not showed.

AFAIK, there is no Developer Plugin for Opera, am I right?

The only errors appearing in Dragonfly are CSS related:

Invalid value for property: vertical-align
   vertical-align: center;

Does any one have a clue about what is happening here?

Thanks in advance!
