I have a question about WCAG 1.0:

10.1: Until user agents allow users to turn off spawned windows, do not cause pop-up or other windows to appear and do not change the current window without informing the user.

What problems are there with operating-system produced pop-up windows? Let's say a user enters data onto a form on a web-based application. The use hits the submit button, the data is validated, and is found to contain an error. If javascript pops an error message, there will be accessibility problems. But if Windows draws a dialog box to report the error (with an appropriate title bar, message text, and standard pushbuttons) is this a problem? What techniques are more accessible than an accessible pop-up window?
