When I load the page with Chrome I see that jquery is loaded (one time); then maskedinput.js is loaded (one time). But then I see MsAjaxJs loaded (below is the copy of the line):

http://localhost:52714/bundles/MsAjaxJs?v=J4joXQqg80Lks57qbGfUAfRLic3bXKGafmR6wE4CFtc1

But I don't have anywhere in my code loading the MsAjax (in case it conflicts with maskedinput.js).

As to possible problem with maskedinput.js, everything is possible. Although, as I said in the initial message, it works in one test page.
And since ASP.NET does not allow me to set up masks otherwise, I need something.

Thank you.
