I have a very specific problem that I've managed to identify, but can't work out how to solve! I have a page from which the user can generate a Word document, which is posted back to the user as a MIME attachment. That's not the problem, as it works with Firefox on the XP machine that I'm developing on. However, on a user's XP machine, after the attachment is opened automatically in Word, all the buttons on the page that use BLOCKED SCRIPT__doPostBack no longer work, as though the event isn't generated. All the same buttons work fine before the attachment is downloaded, its only afterwards that the problem emerges. Buttons that load other pages work fine too, its only postbacks that become a problem.

Its a bit odd, as I can't recreate the problem on my XP machine, and I can't spot any significant difference in the configuration of Firefox either. I assume it must be some client-side configuration issue, but does anybody have an idea of what I'm missing? I thought it might be some security setting that I don't know about, perhaps not in the browser at all? Please help if you can, as I being shouted at!! Regards

 PS I've just noticed that the word "j a v a s c r i p t " has been removed from my post above, where it currently says "BLOCKED SCRIPT", in case that has caused confusion!
