Don't know if anyone knew but there is a update for the touchscreen software on the shark/no name monitors on gooddeals18 .
I tried it on my 8"touchscreen Running xp sp2

from them and there was no problem so far also i look around on the website and found that theres been some hardware infringement .i dont know if it applies to us though .
Take a look at the website under the support section for the drivers
