SmartNavigation seems to be a nice feature - it allows Internet Explorer to handle PostBacks in a very clever way. You don't have to worry about having a long site - it will return to the point where you have been before. Or if you define some events - SmartNavigation will enable you to invoke the handlers without posting the page back to the server.
But: If you are going to program a serious website for users of different browsers (Netscape, Opera, Konqueror or Safari) you need to turn SmartNavigation off, because it simply doesn't work with this kind of browsers.
"document.<id-of-your-control>.focus();" & _
But: Try it with SmartNavigation turned on: It simpy won't work on some systems. The reasons are unknown, but it seems to be, as if IE won't interpret the script correctly.
Sad, isn't it?
