1342024 - Often when I drag a group of messages to a folder, it instead moves the whole window with Mac Sierra

Status: RESOLVED DUPLICATE of bug 1333121

(Thunderbird :: Mail Window Front End, defect)

Description

[Eli]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_3) AppleWebKit/602.4.8 (KHTML, like Gecko) Version/10.0.3 Safari/602.4.8

Steps to reproduce:

This began a month or two ago, it happened infrequently, but now it's a regular occurrence and the annoyance level has gotten to 'ok fine, I'll file a bug' state :)  So I believe that this may have started with the 45.7 release, but I can't be 100% sure.

... I'm currently running Thunderbird 45.7.1 on the release channel ...  On Mac OS/X Sierra 10.12.3

What happens is that 'sometimes' when I go to select a number of messages and drag them off to a folder.  Instead of the messages being drug, the whole window moces instead.   I typically have to stop, click on/off the window a few times, and try again.  Sometimes it works, sometimes it's still stuck moving the window.


Actual results:

The entire window moved around instead of just a few messages being drug to the folder.


Expected results:

The messages should have highlighted and been dropped in the folder.

A side 'bug' I will mention in case it is related, is that sometimes after Thunderbird has been running a while, when I go to drag messages off to a folder, it will actually not show the highlight of what folder I'm dropping it into.  It still works, but the highlight stops working.

This is related to sierra, fixed in THunderbird 52 now near the end of beta
