We have an issue with DateTimeEditBox and MaskedTextBox appears like filled password boxes in MetroDark and MetroLight in customer environment. They are using Windows 7, 64-bit. In our environment the prompt indicators are transparent, and do not appear, as we expect. This only happens when the textbox is focused. Any idea what might be the issue? I've seen in some styles that the PromptIndicator color is based on a binding to the Foreground property of the box. Why does this behave differently on different machines?
We are currently updating to the latest version, but the release notes don't mention a fix for an issue like this.
