I am using the following:

Product : HotJava Views 1.1 binary
Version : build "aa"
Date    : 11/26/97
Path    : /usr/local/java/hjv1.1/[ packages | solaris | win32 | x86 ]
Comments: FCS Candidate

Steps to reproducing the bug:

1. Start HJV (Tested on Solaris only)
2. Wait for the Welcome window to appear
3. Go to MailView
4. Login
5. Select a mail header to read and look at the mail body headers.
 You will noticed that the headers are overlapping which causes garbage.

Note: This only happen if you set the Mail Properties to "Open Compose window" when selecting an address in the Message Viewer.
