SYMPTOMS
If you use Microsoft Remote Desktop Connection (version 5.1 or later of the Terminal Services client) to connect to a server that is running Terminal Services, you may notice that the movement of the mouse pointer is not smooth. The mouse pointer may move with a jerky motion. This problem is most noticeable when you use a painting program such as Microsoft Paint or the drawing tools in a Microsoft Office program.



CAUSE
This problem occurs because the update interval for mouse movement in Remote Desktop Connection cannot be adjusted.
