>>>I am using WWIPStuff from West Wind Connection. I am using the http control to download some files. All has worked well for years. Now I have found two clients who upgraded to IE7 and they now get an error "Win32 API. The parameter is incorrect". Any idea what I must adjust or must I upgrade to a new version? I believe my current version is 4.62.
