I have found tips over the forums on how to improve the screen sensitivity of your WinMo resistive touchscreen
1) When calibrating your screen, tap the cursor hairs as accurately and as lightly as possible. I use a toothpick for this, it has a fine tip. You will notice immediately how much more responsive your screen is!
2) Another method I found was:
a) Install Attached .cab / Reg Tweak
b) Soft Reset
c) Be Amazed at your Screen Sensitivity!
This is a little .cab file / reg tweak created by kevinpwhite (all credits to him)
EDIT: Many people in the thread have said that it has calibrated their screen wrong and they can't navigate it (cab/reg) This has resulted in a hard reset to get the touchscreen back(due to different touchscreen resolutions etc) I will investigate more into this and create a new version, if possible. Please use it at your own risk, and be sure to create a backup of your device.

Hi, dudes, my HTC WIZARD gets "untouchable" after this installation, but i found the way to solve it! =D
1- Download: CeRegEdit (u can found it on Google, with this u can explore your mobile reg trough your PC)
2- Open it (with your cell phone connected in ActiveSync)
3- Go to Tools, and select "Unlock registry" (your registry will be "Editable")
4- Navigate to:[HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\TOUCH] and change this values to your defaults:
"CalibrationData" and "MaxCalError" (you have to found the values for your phone, here in XDA i foud the values for my phone)
I hope to help someone, and i hope than no one had to make an horrible hardreset
Please give me feedback if it works for you!
