Hi, thanks for your reply and link.

Hmmm, that certainly does sound like the issue I'm having, but I don't have the knowledge of experience of trouble-shooting as those posters have.

It is doing the same thing by the sound of it, it only jumps to the front when a Thunderbird window is active and I am using Windows 10 64bit.

I'm guessing there is no solution at the moment?

Thanks.

try turning off he slide show in windows 10 and see if that has an impact.

Right click your desktop Select personalize change the slide show to a picture.

YOU SIR ARE A GENIUS!

I've had this problem for weeks...months even, it's been an annoyance but I've just put up with it.

That is EXACTLY the problem! I had a slideshow set to change every minute. I usually have multiple windows so don't often see the background and didn't spot the pattern.

I've just tested with a static image and then with a slideshow and timed it...it's exactly spot on in sync, when the background changes, the Thunderbird window jumps into focus a second or two later.

I'm sad that I can't have all my nice backgrounds (when I see them), but over the moon that there is a solution!

Thank you so much! :D

Just re-reading what Wayne Mery linked me to earlier in the thread. It does actually say in there about it being linked to a background slideshow issue.

Thanks for linking me to that Wayne, unfortunately I was just being a bit dozy when I read it I think, skimmed over it and missed the obvious points which I can now see were staring me in the face!

Duh!

When the referenced bug is resolved you can have those slideshows back ;) <BEG> However. We are looking for people who are interested to help chase the issue.

Can you reproduce the issue if Thunderbird is "Full screen" (double click the windows heading between the tabs and the minimize widget. I understand it only occurs is the window is in "Normal" mode not full screen or minimized.

Can you reproduce with Thunderbird in safe mode. Help menu > restart with add-ons disabled.

Hi Matt

I'll have a look at that for you now...

OK, I've tested that and:

Firstly, I put the slideshow back to one minute to check I could reproduce the bug, which I could.

Full screen - no issue, works as normal

Safe mode in a window - no issue, works as normal.

So as you say, it seems to just be when it's in a window.

Hope that helps!

In Windows 10, when composing an email, very often the main window takes over and message text gets interpreted as commands. I am not running slideshow.

I saw exactly the same statement on the bug just a few minutes ago. I have no solution to offer you. Perhaps file another bug?

I am having the same issue. Is there a solution without turning off Windows slideshow?

At this point NO.

https://bugzilla.mozilla.org/show_bug.cgi?id=1234317 has a patch waiting for a review. But totally unknown is when it will hit a release.
