Dear Julia Bocchetta,
Thank you for your reply, please be inform that I use windows 7 operating system and I did exactly what you suggest(ask) me to do, but unfortunately it didn’t help and the problem didn’t solved yet.
I did use the desktop keyboard and seems he works properly, also I used an other keyboard and it worked properly too.
I think there is a problem with the keyboard it self .
If I write :
A its written AZ,
S its written SX,
D its written DC,
F its written FV,
H its written HN,
J its written JM,
K its written K,,
L its written L.
If we marked these fault letters on the keyboard we see that they have the same sequence.
Would you please be so kind and consider my request and help me solve this problem, or I need to buy another keyboard.
