In first place, sorry for my english...i am spanish and...

I'm, trying to use addnode. Your version is very good, is the same i am searching, but i have a problem with the thickbox window. When i load my cck content with addnode fields i press the image button (of the improved version of addnode) and the thickbox window is ok but, for example, if i try to use my scroll and them I try to press the button of addnode field again, the window appears in the botton of the screen (in "ie" and "firefox"). I try the same operation in your example and fails again. Try it.
Searching the solution, i think that perhaps the error is in the theme (I use the "deco" theme), but i change the theme (for the "garland" theme) and again, the same error.
I try to change the css too, but nothing changes.

What I want is that the thickbox window appears in the center of the screen always.

¿Could you help me? ¿What's happen?
Is very important for me.

In any event, thank you.
Greetings,

Barry Collins
