I use Spaces to organize the task I'm pursing. In that vein, I often will have a browser window on each Space, with open tabs relevant to that task that Space is used for.
For example, Space 1 is for Work. So in addition to work applications, I have a browser window open with tabs relevant to work. Space 2 is for Photography. And Space 3 is for just general browsing and social networking, etc.
I am easily able to put a different browser window into each space. The problem is that when I restart the computer, all windows appear in the first Space!
My browser is Chrome, and perhaps this is an issue I need to take up with the Chrome team. Or is this a bug in OS X Lion?
Everything @Sung stated in his answer is how I also experience this. Finder restores every window in the correct space no matter what. Safari only does it after a restart. When crashing or quitting it does not remember on which space every windows was located and opens them all on the current space. Interestingly Firefox does not have this problem. Preview is just a mess and basically remembers nothing at all.
I know this post is old and this issue persist up until Catalina but I am hoping that anyone finds a solution.
