After your reply I did some more tests with the following conclusions. 1. I was wrong about perl. IE behaves the same with the perl equivalent script, but requires the user to cancel 2 times. After the second time, you cannot try anymore.
2. The source of the problem seems to be Internet Explorer and not the server nor the scripting language. I have tested the same script under win2k with both IIs and apache and both perl and php with the same results. I have also tested both php and perl scripts on a linux running apache 1.3.14. Still the same problem. After two attempts to download, then hit ok and at the "save as" dialog, hit cancel, IE becomes useles. I haven't tried asp, but something tells me it will make no difference.
