I've been testing SP5 since I received the beta invitation. So far it works pretty well. There's just one or two minor things that I'm trying to reproduce so I can give more details. Other than that, there's also a few sentences in French that are missing. I'm willing to provide them to you, but I'd like to know if you have a text file with the translation strings so I can complete what's missing, or do you prefer posting screenshots of what's missing plus the translation?
Let me know, and keep up the great work! I'll still be testing everyday.
