Powerpoint Issue

Hi there,<br /> <br /> We recently upgraded our computer to a more powerful one and are using Media Shout 5 still. One problem that we are coming across is that every time we switch from a lyric slide to a powerpoint slide and then try to switch back to a lyric slide, the screen goes black and nothing will make it go back to the lyric slides. The only we can do is exit out of the program and start it again and then we can click on a lyric slide to continue. We tried using Media Shout 6 trial version and there isn't the same problem with the same workflow. Can anyone advise on a solution? <br /> <br /> I've checked to make sure that the output settings on the powerpoint presentation is set to secondary monitor but doesn't seem to make a difference.
