[TYPO3-core] RFC: Bug #16250: prototype methods are used to determine the available viewport dimensions in ExtJS plugins

[Steffen Kamper]

Hi,

when i look to firebug and test this:
Ext.get('typo3-docheader').getHeight()
i get 22

When examine the div i get height=49px (FB calculated CSS)

It seems that with position absolute you don't get the real render 
state. I think this was the reason why i used 40 hardcoded.

What was the origin problem, what is different in IE6?
