1743899 - After I click on a mail item, and scroll down to the mail itself. I cannot scroll at all unless I move mouse left/right.

Status: RESOLVED WORKSFORME

(Thunderbird :: Folder and Message Lists, defect)

Description

[JG Berson]

User Agent: Mozilla/5.0 (Windows NT 10.0; rv:94.0) Gecko/20100101 Firefox/94.0

Steps to reproduce:

I click on a mail item in the upper pane.
I mouse down to the mail item displayed in the lower pane.

Actual results:

When in lower pane, I cannot scroll up or down until I first move mouse left/right. Then it acts normal to mouse movements.

Expected results:

I should be able to scroll freely after I enter the lower pane.
This issue only started recently. It was normal up to last (or previous) update.

What happens after help > troubleshoot mode ?

Comment 2

[JG Berson]

I never tried troubleshoot.

Also, noticed, there is a time delay of about 2 full seconds before the mouse is active. If I just move the mouse to the lower pane and leave it alone, in about 5 or 6 seconds it becomes normally active.

It seems others have similar problems.

Just tried troubleshoot. Mouse is normal.

I also just noticed it happens more so when I delete a mail item using the "delete" in the header pane, the next item selects and I mouse down to view.

I experience the same problem, with a left/right (not upper/lower) pane arrangement on version 91.5.1 32-bit on Windows 10 (but have observed this behavior for several weeks). I select a message in the main list, then move the mouse to the message pane and try to scroll, but nothing happens as long as the scroll wheel is moving. A slight movement of the mouse pointer unlocks the scroll. Alternatively, just waiting a couple of seconds and trying to scroll again also work. But the first scroll after the mouse pointer comes to a halt never works.

Just an update: I find if I move the mouse down into the mail text area (lower pane) and immediately left click in it, the mouse will usually behave after that. It's now become a habit.

I've been having this problem for a long time now, and I didn't bother looking into it because I assumed others were too and a fix was coming. I didn't realize this is such a rare bug.

The problem is basically as others have described. I can't scroll with the mouse until I either wait several seconds, or I in some way perform some mouse movement/click ritual.

This is really obnoxious because I have assigned an extra button on my mouse to delete. I also have a thumb paddle for scrolling.

So I'm used to holding down the paddle, to quickly scroll down through messages, while I tap the delete button to delete it and move on to the next message. I could quickly go through a dozen or two emails in well under a minute, and I never have to let go of the paddle once, unless it's an email I want to keep.

So needless to say, this very annoying bug has really slowed me down.

Oh and I tried troubleshooter mode and the bug persists there, too.

I would add that to the original post but there doesn't seem to be a way to edit posts on my end.

JG Berson do you still encounter this when using a current version beta ?

Comment 9

[JG Berson]

Thanks for the heads up.
I am so used to always clicking when opening an email, I never noticed that it seems to be fixed.
I'll check out other instances and if fixed, I will close this bug.

Not fixed yet. But some emails seem not to have the problem and others need the click or L/R swipe to initiate scrolling.
So far I can't see any difference between those that are "fixed" and those that are not.

I'll keep checking.

Mouse, JG B,
Does this reproduce with version 115?

Comment 12

[JG Berson]

I have not had this problem for quite some time now.
I just d/l'd 115 and seems OK.
I would consider it fixed
