I am a Windows and a Mac user. Mac Mail (Leopard) has the following problems: 1. Cannot handle wmv or pdf in an attached email; they only work if attached to an original email. 2. Paste into an email grabs signature and moves it forward 3. Several other attachment types are unreadable. I have to continually use my Windows client to read 5-10% of my email. Am I missing something? How can Mac expect Windows users to switch to Mac if you can't read all email types?
