Password fields "revealing" problem

Has anyone noticed that even the .NET 2.0 windows forms (not sure ASP)
password field is vulnerable to the "password revealing" problem? To be
clear, I refer to the fact that it is easy to run a free program that simply
takes the field showing the asterisks, and showing you the password behind
it.

If Microsoft solved this problem in their own applications, why didn't they
solve it for this commonly used control?

Any tips on best workarounds?

thanks
