490208 - Thunderbir compose window freeze (you can not type) while receiving new mails

Status: RESOLVED INVALID

(Thunderbird :: General, defect)

Description

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; pt-BR; rv:1.9.0.9) Gecko/2009040821 Firefox/3.0.9
Build Identifier: 20090302

Yesterday I was composing an e-mail and every 10 minutes the window freezed (I could not type or do anything until the antivirus processed the income mails) because I have all my accounts set to retrieve new messages every 10 minutes.
But when you are composing a message, it should NOT freeze (block all window events as typing) while processing the incoming mails. I found it VERY DISTURBING.
There are two possible solutions: 
1- To improve the isolation between the compose window events thread and the events on the rest of the Application so that receiving e-mail will not block "typing" in a compose window.
2- Or.... a New Feature in Preferences, an option "Pause receiving messages while composing for... minutes" with a configurable timer initially set to 20 minutes. If the user close the compose window, it cancels the timer and starts receiving messages normally. 

Reproducible: Always

Steps to Reproduce:
1. Have one or more accounts set to retrieve new mails every 10 minutes
2. Start a new mail
3. When Thunderbird start to connect to server to retrieve new mails, try to type in the compose window
Actual Results:  
You can not type or do anything in the compose window, until the process of incoming messages finish.

Expected Results:  
You should be able to edit your new message independently of the other Application processes.

I don't know if this behaviour is caused or not by Antivirus activity or Thunderbird itself. I used AVG 8 (free) and it processes incoming mails but I suspect it is Thunderbird bug.

Sorry for my bad English, I ate a lot of "s" for the third person verbs.

The amount of time spent in composing that message was big because I was choosing many files to attach to the message, that's why I took me this long time to finish writting the e-mail.

An edit post feature in bugzilla would also be appreciated, to correct those ridiculous typing or English errors.

This sounds very much like a problem with AVG. Please check http://kb.mozillazine.org/Thunderbird_:_FAQs_:_Anti-virus_Software, an AVG support forum and other support groups via http://en-us.www.mozillamessaging.com/en-US/support/

If you still have trouble after consulting these other  areas, please comment in the bug

Thanks, as you read above I had suspected that, later I will do some tests and if the problem persists I inform you. Best Regards
