One of my West Wind Web Connection customers (but this also applies to ASP.NET) recently posted a question regarding a page that wasn't working correctly when using the Back button. The behavior would be something like this:
Go to the page
Click a link that causes a __doPostBack() to occur
Click the Back button
Click on a regular Submit button
What happens is that the Submit ends up re-executing the __doPostBack() operation, rather than firing the button click.
It's interesting, because...
