No Second OneDrive Connection Without Logging Out

In the Power BI Service, I can connect easily to a file in my Personal OneDrive. However, after I do so, I need to log out of Power BI and then log back in to Power BI before I can connect to another one. Any attempt after the first one results in the OneDrive - Personal tile going gray, as it was selected, but it fails to bring up the OneDrive dialog so that I can select the file to Connect.
