file save instead of open?

Hi,

I try to submit following form and get just the 'open dialog' in Firefox
1.5. Why that?
[form]
<form action="./insert_new.php" method="post" name="check">the values you're
going to submit are following:<br>
Systemname: Test<input type="hidden" name="systemname" value="Test"><br>
Price: $14<input type="hidden" name="price" value="14"><br>

Monitorsize: 14"<input type="hidden" name="monitorsize" value="14"><br>
Additional monitor: yes<input type="hidden" name="addmonitor"
value="yes"><br>
Age: 12 months<input type="hidden" name="age" value="12"><br>
Condition: broken<input type="hidden" name="condition" value="broken"><br>
Your name: Ron Eggler<input type="hidden" name="name" value="Ron
Eggler"><br>
Your email: ron (AT) rideon (DOT) ch<input type="hidden" name="email"
value="ron (AT) rideon (DOT) ch"><br>
No picture was added<br>
<input type="hidden" name="action" value="insert"><input type="button"
value=" Back " onclick="history.back();"><input type="submit" value="
Submit "></form>
[/form]
