can anyone tell me why, when viewing this page in a webbrowser control, the "Log In" button does not work?

https://www.oldnational.com/

if you leave the fields blank, the java validation seems to work, but entering even garbage into the Username/pass fields and clicking "Log In" does nothing!

if i view in an IE window, it works just fine.

the button wont work even when simply viewing the page in a webbrowser control!


-tearing my hair out over this, so please help
