A few points: * Personally, I find it frustrating when applications (on the web) automatically move my cursor from one box to another. Like when typing in a date and there are three boxes for month, day, and year. I type in 11, press <tab>, and type 24 to realize that I'm in the wrong box. Maybe that wouldn't apply in this masked input fields case since the interface is a little different but I can't say for sure without testing it. Overall, I'm not very happy with applications that move my cursor around for me or select text automatically. Like when you click into a form field (phpMyAdmin comes to mind) and all the text is automatically selected. * Even though "clientside validation is all about usability" many people don't understand this and still use it as a security measure.

A proper form architecture has many layers of usability and security. 1. Server-side range/format/logic validation after submit, but also before submit using Ajax. 2. Client-side JS to show errors onblur and help the user enter information properly. 3. Maxlength on every field. 4. Ordering a long selectbox based on likely entries being first. 5. Etc etc etc. A good form doesn't get in the users way, doesn't move the mouse in an unexpected way, doesn't annoy the user. A good form helps the user. This takes alot of work and design. With that said, there are exceptions to every rule. With great power comes great responsibility. This topic is huge...maybe worth a book. Form Design. Glen
