When you set the focus to a password field in an application by holding a pen near the field, the floating in-place Tablet PC Input Panel icon does not appear. This problem occurs if the application is created by using the Windows Presentation Foundation (WPF) subsystem feature of the Microsoft .NET Framework 3.0.

This problem occurs because WPF does not use the standard accessibility model for password fields.

To work around this problem, do any of the following:
| • | Open the input panel by using the Input Panel tab instead of the Input Panel icon. |
| • | Use the ITextInputPanel API to programmatically open the input panel. |
