PickyPerkins,
I use Netscape Communicator 4.79 and I only use it for email. I use IE as my browser.
BLUE SKY THINKER
I think I am getting a little confused too. If you like I could sent you two emails, one with a test file ending in .txt and another with a test file ending in .txt.pif to see what happens. (Do not worry, I will create the .txt.pif myself with notepad and it will just be one line of text inside.)
That way we will know what your email program does with each file type.
Take Care,
Richard
