glass2K alternative anyone

[Tripo]

hello this app is great.

But I´m looking for an alternative to this.

http://chime.tv/products/glass2k.shtml

But What I want is the same but it should automatic make all windows transparent.

in glass2k you must rightclick on the window you want to be transparent or press a hotkey.

I want it to always automatic make all windows transparent.

Does anyone know of a transparency software that do this automatic.

That must work on windows2K good if it works on win98 to.
