Nasty E-mail Opens When I Push Delete!!!

Hi!

I use the mail previewer Poptray 210. Today I got an e-mail from someone I know, but which had a nasty-looking reference line. I decided to delete it, so I marked it and hit delete and much to my surprise, this opened a huge screen full of code with the word confirm and ? at the top of all the code. I followed the screen to the right, moving the scroll bar as far as it would go to the right at least 10 times before I came to the end of this window and closed the e-mail with the X in the corner. I tried deleting the same e-mail with a right click and the same thing happened, it opened. How can I get this out of my mail previewer so it doesn't make it to my Outlook Express?

I was able to delete this when deleting it as part of a group of other e-mails. I'm waiting still to hear what it was.
