Screen blanking no longer works after Thunderbird "new email" alert

[Jeff Stewart]

Screen blanking is enabled, set to 10 minutes. Works fine. Launch thunderbird, with option to display alert when new email arrives. After receiving new email, thunderbird displays alert. Following this, the 10-minute screen blanking no longer works.

If you are getting frequent emails then perhaps that is keeping the display awake.

Please try turning off the options in Settings > Notifications > Thunderbird
