I have windows 7 64 bit on my computer with internet explorer 8. Whenever I click to download a file (such as zip) I get the typical open / save/ cancel box. I would like to always open the file automatically without the prompt. The one problem however is that I don't get the typical checkbox that says "ask before opening this type of file" Its not grayed out ...its missing. I would like to uncheck it so I can automatically open my zip files. I've searched and nobody else seems to be having this issue.
