Status: RESOLVED DUPLICATE of bug 261392

(Thunderbird :: Message Compose Window, defect)

Description

[Enrico]

User-Agent:       Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9.2) Gecko/20100115 Firefox/3.6
Build Identifier: Thunderbird 3.0.1

When I paste HTML formatted text the undo function does not work, i.e. I cannot undo the paste operation.



Reproducible: Always

Steps to Reproduce:
1. create new message
2. recipients an subject can be empty or filled
3. copy text from a web page (did not test with other sources) 
4. paste text in the message body
5. undo does not do anything. the function is enabled but it has no effect.
Actual Results:  
nothing happens

Expected Results:  
undo the paste

I have noticed this on OS X 10.5 and 10.6

When pasting html the editor in general does not behave very well, for example moving the text cursor around skips paragraphs, or the cursor gets stuck. (I noticed something similar in earlier versions too, but the undo problem is new to me)
