Text Imput is stumbling if nvidia drivers are installed

Hello

The input of text is stumbling on my computer, if the GeForce driver
for windows XP (http://www.nvidia.com/content/drivers/drivers.asp) is
installed. I am pretty sure that the driver is the reason. If I use
another old driver, the problem has gone.

My system is as follow.
Operation System: XP Home SP1a
Grafik board: ASUS V8170 DDR 64M (with NVIDIA GeForce MX440 GPU)
DirectX: 9c (I had 9b until some weeks ago and the same problem)


I wouldn't rather use the older drive, because this one caused other
problems.

Thanks for you help in advance!
