User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8) Gecko/20051111 Firefox/1.5 Build Identifier: Thunderbird 1.5 file version 18.104.22.168 This problem occurs when one adds text and images to a message BEFORE selecting the addresses. It does not occur if one selects the addresses PRIOR to composing the message. I open a new message and start inserting text and images. The images are not large, but the amount of text can be. Once the message is complete, I then use my mouse to select several addresses for the message -- usually more than ten. Once I have selected the addresses and used my right mouse button to add the names to my "to" "cc" or "bcc" field, CPU useage soars to 100%. Thundbird begins to very, very slowly add each address, often taking one minute to add each address. More often then not the program stops responding Reproducible: Always Steps to Reproduce: 1.Open a blank message 2.Copy and paste a lot of text several times -- try to five or six hundred words 3.Highlight the addresses of those you want to receive the message. Pick ten or fifteen addressees. 4.Use the RIGHT mouse button to add the addresses to the message. Actual Results: Once the addresses are selected, cpu useage hits 100% and the program eventually stops responding Expected Results: Thunderbird came to a virtual stop; hogged 100% of the cpu; stopped all activity on the computer; and then showed the tag "program not responding" Under the prior versions of Thunderbird, the addresses would have been instantly added and the message would be ready to send.

When I tried to add recipients it maxed out the cpu usage, like you saw, for about 30 seconds, then I tried adding a few more and it froze TB and had to kill it. I am running XPSP2, Athlon64 2800, 1 GB RAM. I think it has to do with the message length itself. I usually write fairly short messages, and if I have added an attachment (even fairly large ones - several hundred MB), then added the recipients I have not had a problem. (Maybe I've just been lucky.)
Maybe a duplicate of bug 315412. Try disabling spell checking to see if it helps.
In email from reporter: I think that you are correct! I disabled spell checking and my nightmare ended!!!!!!! Duping... *** This bug has been marked as a duplicate of 315412 ***
