Window size in Mythbuntu Control Center (MCC)

my Philips LCD - TV has a resolution of 1024 x 768 Pixels. If I try to backup my database in the Mythbuntu Control Center (MCC), I can't see the "submit" button, because the Window is too large. See Image. You can't find the submit-button and other buttons on the bottom of the window. And I can't move the window higher and I can't resize the window. Would you mind to select smaller dimensions the the MCC Window or to move the buttons to the top of the MCC Window?

Best Regards,
