Hello all,

I have an interesting issue with opening attachments that are included in browser enabled forms.  The files have been added as 2007 excel documents with the xlsx file type.  When the attachment is opened from a browser enabled form it tries to open as a zip file.  It also tries to save as zip archive when you try to download.  I also have seen cases in which it tries to open as a aspx file.  So what is interesting is that from my client it works as intended.  I can call up the form and it opens fine.   Is there a browser config I might have to look at?  These users are IE 6 users.

 Interesting issue. A Google search revealed some very interesting things I was not aware of:
