It is a little longer in some situations. If you read a message of yours, additional icons will appear. That will make it longer. Like Solution, Help and Update will appear. Is that a possibility for you to enlarge a little bit more the message width? You're working with 1024 at least right? If you work with a larger resolution, you should be ok with a larger width.
