285970 - thunderbird is very slow after it has been minimized

Status: RESOLVED DUPLICATE of bug 76831

(Thunderbird :: General, defect)

Description

[Andi]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-GB; rv:1.7.6) Gecko/20050311 Firefox/1.0.1
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-GB; rv:1.7.6) Gecko/20050311 Firefox/1.0.1

If I click on the task of thunderbird in taskbar, thunderbird is getting
minimized. That's normal.
But If I click again on that task, thunderbird appears again - but very very slowly.

Additional, I saw in the taskmanager, that thunderbird uses only 800kbyte of
memory in minimized mode, but over 9 mbytes in normal mode.
Perhaps, thunderbird takes a lot of time to reload some things into memory?

I used several versions - thunderbird 1.0 , 1.0.1  and 1.0.2 - but the problem 
appears in all versions. 


Reproducible: Always

Steps to Reproduce:
1. minimize thunderbird 
2. wait some time
3. click on the task of thunderbird to view it

Actual Results:  
thunderbird doesn't show directly the whole window with all items,
instead it loads one item (listbox, button, etc.) after each other...
after a few seconds, it has load the whole window with all items.

Expected Results:  
getting faster!
