Ok so first off.....no thanks Apple for taking away the nice pref pane to control app space assignments. Doing it with a right click on the dock icon is painful. 
Anyway......assigning an app to a space works ok for some apps....but others it has a problem with.
For example.....the latest BBEdit......I have it assigned to Desktop 2. If I click on the app icon.....I'm taken to desktop 2. Ok that's good.....however, by default with me.....BBEdit doesn't open any windows.
So, say I go to Desktop 4 and I click on a .php file to edit.....instead of being taken back to Desktop 2 (like I was in SL), the BBEdit window opens in Desktop 4.
This also happens in my FTP editor (YummyFTP).
I think is has to do with apps that can be open....but not have any windows open. The Adobe apps used to have these problems in SL....but things like BBEdit and YummyFTP worked correctly in SL.....so I know it's a Lion issue.
