I just clicked into the Lightning calendar for first time. It blinks continuously and I can't do anything there. Thunderbird 45.1.1 Windows 7 (desktop PC)

If you are truly running Thunderbird 45.1.1 and Lightning 4.7.1.1 then those are the correct version to work together. I would go to the Add Ons tab and remove lightning and reinstall it.

Thanks. That fixed it. All is working well now.

What I'm doing:

I'm not experienced with computer calendars. I'm very experienced with computers but for whatever reason I always use paper calendars.

I have microsoft 2000 outlook but find it unwieldy and never figured it out. So when I noticed that Thunderbird has a calendar, I decided to try it. I've had thunderbird but I never used the lightning calendar on thunderbird before.

I recently updated thunderbird to latest version. Then clicked on calendar to see what it's like.

What happens: Parts of the screen blink on and off. The areas in the screenshot blink in and out of view. When "on" or "in view", I can see them as in the screenshot.

When "off" or "out of view", those words/numbers/times are plain white as if they are invisible or not there at all.

I'm not able to type anything anywhere.

What I expect to happen: I expect it all to stay in view so that I can type tasks into the calendar.

This really sounds odd. Are you using any other theme than the default one?

Sorry for the delay in replying. Now I have a new issue.

I had to reboot my computer. When I logged into Thunderbird again, I got a new message:


This pops up on my screen:


quote ----

Mismatching Lightning Version

The binary component required for Lightning could not be loaded, likely because the wrong version combination is being used. You currently have Lightning 4.7.1.1 installed, but should be using a version from the 4.7 series. --- end quote ----

How do I fix this?
