The form feed character (0x0c) in a mail message is always rendered as thousands of empty lines. I'll post an example message as an attachment. I'm using build 2002041203.
Created attachment 79181 [details] A mail message which has a form feed character Using the attached message, the bug can be verified with these steps: 1. Load the attachment to your HD 2. Open it with mozilla or send it to yourself. --> The message has thousands of empty lines before the "Message continues" line.
viewing the attachment does not show the bug on XP, 2002041408 Sending the page to myself in mail and then opening the mail doesn't show the bug either. (Vaguely related: There's bug 106311 about the code displaying as a "square")
I tested the bug in another Win2k machine and there the attachment 79181 [details] was shown as expected. Some differences in the setups - Different user profiles - Dual AMD (has the bug) vs. single Intel (The attachement 1 was incorrectly referenced in my previous comment)
This has been fixed in recent builds. The form feed now shows up as a small rectangle.
Since this does not occur anymore, resolving as worksforme.
