Slow Draw Anomalies  

Using Draw mode can be slow on certain Windows® CE machines. For example, 
drawing a curve inside a draw application may produce ragged lines and the cursor may 
lag behind. The "IOPollDelay" parameter adjusts the behavior of draw mode. Adjusting 
the default value of this parameter may improve the behavior and appearance of the curve 
without affecting overall performance of the Windows® CE system. You can add this 
parameter to the system by editing the text file TwParams.reg found in C:\MT7_CE\x86. 
To add this parameter with a new default value insert the IOPollDelay line after the line 
below:  

[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\TwTouch\Parameters]   
"IOPollDelay"=dword:1(value) 

A value between 1 and 20, such as 10 may work best for your particular application. 
After adding or modifying the value of this parameter, you need to rebuild the 
Windows® CE image and test the draw behavior.
