578932 - Lack of folder highlighting during drag&drop of a message

Status: RESOLVED INCOMPLETE

(Thunderbird :: Folder and Message Lists, defect)

Description

[David Hollman]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.0; en-GB; rv:1.9.2.6) Gecko/20100625 Firefox/3.6.6 ( .NET CLR 3.5.30729; .NET4.0C)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.2.4) Gecko/20100608 Thunderbird/3.1

Most of the time when I drop & drop a message into a different folder, the target folder under the mouse cursor does NOT get highlighted.  I did not notice this until the current version of TB.

This is a little bit inconsistent, in that sometimes the highlighting does work.  However the non-highlighting happens the vast majority of the time so it is easy to reproduce.

IMO this is slightly more severe than a purley "cosmetic" issue as it does affect ease of use, in that it makes it a bit harder to make sure you're on the right folder, and also it was initially unclear if the DND would work.

Reproducible: Sometimes

Steps to Reproduce:
1.Select a message in the message list
2.Drag it over the list of folders

Actual Results:  
The folder under the mouse is not highlighted


Expected Results:  
The folder under the mouse is highlighted

What mouse pointer do you get, the [] or the (/) one?
Trying to figure out if this is actually the same as bug 578934 or not.
