ThumbJam not accessible with Voiceover in iOS7!

Hi all, Having updated to the latest version of iOS 7.0.4, I have discovered that ThumbJam is no longer accessible with Voiceover. When I click on the Sound button, for example, the Voiceover focus moves automatically over to the play area. When I try to click on the button a second time, it automacally selects one of the options in the sound category. Have any of you noticed this, and have any of you been able to figure out a work around? Thanks in advance! Kind regards, Siena.
