I am trying to apply the telerik metro theme to the WPF controls. While most controls looks OK, the PasswordBox somehow received a strange double border (see attached image). This issue seem to only affect the Metro Theme, other themes such as the Windows7 Theme looks ok.
Unfortunately, it is true that this problem exists in our latest internal build (2012.2.820). We have already fixed it and changes will take effect in the next Monday's internal build. Please excuse us for the inconvenience.
