Thanks for your reply. However, if the answer is to get a new host, then it is easier for me to use a board which works better. Again, I like SMF so much. I think it is the greatest board ever created. but I keep wondering how comes that attachments work fine on other boards while on SMF they are a bit problematic? What should I tell my host? I mean what is wrong with their server? In addition, Firefox works fine with attachments. The problem only insists in IE7. Even previous versions of IE work fine as well.
Now as you saying it, I wonder whether the problem lies in the way SMF stores attachments?
