Perpixel rendering

The full name of my graphics card is VIA S3G UniChrome Pro IPG.
Does it support per ixel rendering?
I use a sofrware called WindowBlinds which can change computer themes and make window borders translucent, colourful etc.
But whenever I choose semi-transparent borders, I get a prompt that My hardware does not support per pixel rendering. Try to get driver updates.
I got an update but this does not resolve my problem. My graphics card manufacturer tells me that it is the latest. I bought it only two months back. My driver version is : 6.14.10.297. Please suggest me some ways to resolve this problem or provide a driver which supports perpixel rendering. The Video Memory is 64MB approx.
The exact error message WindowBlind Gives is this:
WindowBlinds version : WindowBlinds 6.0 (build 32 x86)
WindowBlinds is installed correctly on this PC
WindowBlinds appears to be activated on this PC
Your machine does not support per pixel borders on WindowBlinds skins.
This is because :
Your computer graphics hardware does not support acceleration of per pixel alpha. WindowBlinds requires this for per pixel alphablended borders as without it performance would be poor. Please see if you can obtain new drivers for your graphics hardware. Recent ATI & NVIDIA boards should support this feature. Onboard graphics tend not to.
It appears you have enabled limited per pixel mode, so WindowBlinds will support per pixel, but with no hardware support.
