Can you give some examples? It works fine for me. I do agree with Berthold that 'normal' programs might be a little hard to use with touch because the buttons are so small. For those, I usually just use the mouse.

Here are a couple of things that you can try to get better performance:

1) Make sure that your screen is clean and free of dust. This is very important and can effect touch performance.
2) Run the hardware diagnostic program. If you go under the main Help and Support menu, there will be help for TouchSmart. You'll find the program under there.

Hope this helps!

There is a hidden touchscreen configuration on the Touchsmarts that is much more accurate than the Hp Touchscreen Configuration in the control panel.

Tap the Scroll Lock key 5 times when on the desktop. This will cause the cursor to move to the upper left hand corner. Press hand hold your finger on the cursor's location untill you hear a long beep and release. The cursor will move to the upper right hand corner, repeat previous step. After you have done this in all four corners the cursor will move to the centre of the screen and the touchscreen will be recalibrated, accurately.
