First, the only reliable way to set the size of the dialog is to set

Secondly, make sure you don't have a style
Why not use a HTML panel and inside define a HTML table with the
widgets in the cells? I rarely use things like FlexTable,
HorizontalPanel or VerticalPanel. Usually all my forms are a
combination of pure HTML and widgets. If you don't need IE6 support
then I can show you some neater ways of laying
If you need to dynamically modify the table I would stay with
FlexTable. Working with the DOM on tables is kind of messy.

I've stepped through the code and there is no requirement to
unregister handlers explicitly. Each widget has a handler manager (as
member variable) that manages its handlers. If a widget is removed
from its parent or its parent explicitly clears it then the registered
handlers will get cleaned up
