My dashboard keeps flashing/refreshing, how do I stop it?

It sounds like you accidently enabled the dashboard refresh when you created your dashboard.

Click the pencil icon next to the print icon at the top of the dashboard,  reset that dashboard refresh period to 0, and save.

Yurbi will automatically display the latest results each time you load the dashboard,  the refresh feature is designed when you have the dashboard on a display TV where no one is interacting/trying to actively drill down or use the dashboard.
