Join Problem on PS since adding Table Ninja

[BAM21]

When I select join table in scanner, since I added Table Ninja, the Poker Stars Lobby comes up with the table selected but the "join table" box does not appear. Sometimes the selected table does not even appear - the lobby comes up with a different table.
Please help.
Thank you.

Nevermind - this seems resolved when I selected "Automatically accept waitlisted seats" in the Opening/Closing tab of Table Ninja. I'll repost if I the problem comes up again.
