[jQuery] BlockUI 2.X ver. not ful screen overlay in WSS 3.0 new item list form


Hello everybody,
first of all I want to say BlockUi plugin is very useful, perfect...
but now I've tried it in my WSS (Sharepoint) web form. I want to block
whole page, but it blocks just part of screen. When I click on
horizontal or vertical scroll then the screen below is not overlayed
and look like not blocked...
Please help me to solve this issue...
Thank you Vasek - Slovakia
