Description

[[e-mail]]

Attachment: Calendar-error.png

User Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:45.0) Gecko/20100101 Firefox/45.0
Build ID: 20160407164938

Steps to reproduce:

After last update (Lightning 4.7 with Thunderbird 45.0) I can't see description of existing tasks when I'm trying to edit them. Also I can't add description to new tasks (filed is read-only).
When I'm trying "Change task to mail" description is visible (it becomes content of an e-mail).
See attachment.


Actual results:

Description of existing tasks is not visible and I can't edit it.


Expected results:

Tasks' description should be visible and editable as usual.

Sorry for that bug - upgrade Exchange EWS Provider v3.8-beta2 resolved problems.

Hi,

please check Tools > Error Console for error messages and post them here.

Please disable other extension and retest. Your screenshot shows that you have installed an extension that overlays the Task dialog and breaks it. I have seen this problem reported before but could not find the bug report on first search.
