Not sure if it works for you, but that was my experience.
Actually, the same was true for me, I just missed it happening last time when I closed the popup without thinking (it was partially covered at the time). However, now I just get as far as the login window and close the popup, and then after I log in it just shows the ship flying through space instead of switching to the game's main UI. Am I doing something retarded here? D:
Edit: And yes, I reinstalled the client before figuring out that my problem was the same as Blizt's for his laptop, so it's not file corruption or anything. ):
