Using OnlyM with 3 screens (laptop, second monitor and Hall screens)

[AllanChes]

We are using a small screen laptop and are trying to use a second monitor to give more screen space at the Sound Desk. So that the JW Library will display on the Hall Monitors, we have had to choose the second Sound Desk monitor as the "main screen" for the laptop, otherwise the JW Library displays on the second monitor, as does OnlyM. However, when we choose the second monitor as the "Main screen", the Library is fine and displays on the hall monitors but OnlyM's second screen disappears. When you mouse over OnlyM on the task bar, it is showing a second screen but it is just white and the second monitor loses it's image but nothing is displayed. If you click on the mouseover thumbnail nothing happens - the image does not appear on any screen. Is this a 'bug' or is there some other way to get it to operate with 3 screens? Thanks for any advise. Allan, Nuriootpa Congregation, South Australia
