Ink programs may not work correctly on a digitizer in Windows Vista

This article has been archived. It is offered "as is" and will no longer be updated.
In Windows Vista, ink programs may not work correctly on a digitizer. For example, you may experience symptoms that resemble the following when you use a stylus to input ink:
  • When you draw but do not lift the pen, nothing appears on the screen until you lift the pen. Then, all the ink that you used to draw appears.
  • When you try to draw straight lines, unexpected jagged lines appear.
These symptoms occur if the following conditions are true:
  • You are using a touch screen device on a Windows Vista-based computer.
  • The touch screen device is set to use a digitizer.
  • The Stylus and Touch input program was written by using the Windows Presentation Foundation (WPF) Host. The input program is hosted in Windows Media Center or in Internet Explorer.
These problems do not occur if you use a mouse instead of a stylus to input ink.
