If there was an equivalent of Windows Modal dialog box in web applications, a similar one can be found in ICICI Direct stock trading application.
1. They keep showing the above dialog box requesting you to update your information and not providing you an option which says nothing to update.
2. If you choose the option "Will change later", their later is hardcoded to be "Just Now"
Now it is understandable that web applications can have errors pushed to production, though it is scary for a financial site.
What is not understandable is the response of their customer support at their call center:-
1. Sir there is a technical problem with the site, it should be fine by tomorrow ( oh yeah, you dolt you haven't even heard my description of the problem ).
2. Sir please click on trading ( ofcourse you doofus, I know how to click on trading to make the screen go away but it comes back when I click something else )
