Possible? making a programme stay in a specific 'space'

System Preferences > Exposé & Spaces > Spaces > Application Assignments
Add any apps to the list with the + button and assign the space you want.

 

That's not what he is talking about. He wants that window to not budge, even if he drags it away kind of thing. What you are talking about is having something OPEN in that space. It can still move around freely if desired. (or undesired, as evidenced by office 2008 )

Stampax: No, I do not think that is possible. What would be the value of that anyway? It's not like anyone just "accidentally" drags a window, hits the spaces hot key, and places it in another space, all unintentionally.
You might be able to make some sort of script to do it, but I kind of doubt it.

 

If that's what he's talking about, I agree: I don't think it's possible, like it is in Windows. Even in Windows, it's not anchored to the space where it can't be moved. Windows just allows you to have an app "remember" where and how big to open a window.
