Thanks - this has been very useful. It is definitely happening for me without opening a new page/tab in the browser, but is very inconsistent. A bit more information: my site guides the user from one page to the next, but occasionally loops back on itself to an earlier page, depending on user input. This problem seems to occur (inconsistently) when revisiting pages they've already been to. I suppose there is some sort of conflict with the _formname. Assigning a unique formname should do the trick. Thanks again, Neil
