Enter button causing trouble..

One of our users seemed to be getting kickout out of a protected area of one of our applications after only minutes. This person was the only one reporting this problem, which seemed odd, but searching for other with similar issues uncovered the issue whereby in II6, if resoures get maxed out for an application pool, site may get recycled, resulting in lost application/session variables. The recommended solution wast to request that your application be put in its own app pool with all recycling options disabled and the recycle worker process set to recycle only once during the day at a set time. I made this request to our host and they kindly agreed. That seemed to fix the problem. The user said she was no longer getting kicked out. It turns out, however, that she discover the root of the problem herself and it wasn’t the application pool issue. After selecting a number checkboxes in a form she would hit the enter button, not click the submit button. That was the problem. Not her fault off course, but a pretty big problem from a useabiltity perspective.

I’d never seen this behavior before, but after a little digging, it looks like it was a big enough problem to address in 2.0. Some comments on that post led me to this post which will solve the problem until 2.0.
