Jamie: A flashing power tally usually means that there is a clock problem. It is possible that when running stand alone, the Mbox Pro is running on its internal clock & when you connect it to a computer, it reads a setup file that prompts it to look for an external clock.

Here's what to do...... Open the Mbox Pro control panel either from within Pro Tools or just the stand alone one. Click on the "Setup" button. You want to see the "General Setup" page. If the "output setup" comes up, click on "General Setup." Look for the Clock source selection. There are 3 choices. If you are not using an external clock generator or using the s/pdif inputs, choose the "Internal" option. This should stop the blinking power tally & allow you to use the Mbox.

I hope this helps.
