It is just the paper airplane that has disapeared. The rest of the "tool bar," looks normal. I should also mention that I have several hundred e-mails in my "Sent" folder. Could it be a memory problem? I don't want to delete them and I'm not sure how to save them to a CD. When I drag them to disk they jump back to the sent folder.
Sounds like a major problem with your Mail application. Have you deleted some files by mistake in the library or application folder? I would suggest you to reinstall Apple Mail. There is a software that can install only the Mail application not the whole OS. Go to versiontracker.com and search for it. I think the software was called something like "patition"!?
Hope you get it fixed! I love the Mail application and I don't use Entourage :)
Thanks to you good people that tried to help. I have since found the solution to the problem - a rather simple solution. A friend of mine came by to help me out . He is a "Windows," user and he clicked the upper right button with the intentions of closing out. This reverted the toolbar back to it's original look. My daughter, who is a "Windows," user had been the last one to use it and this is what she had done. The top right button is one I never had need to click on before which is why it never occured to me to try it.
