Hello,
I recently bought a all new S7 (1 week).
I am really happy with it, it's incradible, but I have a rea problem:
Track pad is not going straight in vertical direction, but the mouse is displacing step bby step...
This is very inconfortable to touch some little internet links, mouse is doing like scales... 
Is it a simple solution?
Precision : We bought 2 S7, one for me and one for my compagny's partner : He has the same problem!!
Can you tell me what I have to do? Is I have to give it back to acer, do I have to do it by the internet store I used to buy it?
Thanks a lot for your wuick answer, it's pretty embarrasing...
Gwenaël
