"File Download Dialog" open twice

[Yannis]

In my HTML page I have a link to dinamically generated
file of type plain/text. I use for anchor target the name
of hidden iframe on same page. Everything is ok with
downloading of this file, except that "File Download
Dialog" is open twice if you click OPEN. Could somebody
suggest resolution for this problem.
Thanks.

I found one solution but I don't like it.
Try this:
1. Click "Start" -> "Program Files" -> "Windows Explorer".
2. Click "Tools" -> "Folder Options".
3. Go to the "File Type" tabs.
4. Highlight the filetype (example :"TXT")
5. Click the "Advanced" button.
6. UNCHECK the option "confirm open after download".

Any new and tricky ideas?
