Hello,
my tablet is quite old, but is recognized by win7.
The digital pen has got something to press, but when I do so on cs3 or paint brush, nothing happens.
The brand is called acepad.
Anything needed to be setup in order for the tablet to go to work?
Thanks
Jack

Sounds like you are probably having driver problems. Most likely, this product doesn't have drivers that are compatible with Windows 7.

You can try and look for the correct drivers online (if they exist) if you know the exact model of drawing tablet you have. But you may be out of luck.

Alternatively, are you making sure that you are selecting a drawing tool in CS3 before attempting to draw?

I am using Acecad Acecat Flair,

checked google seems the driver doesn't exist.
Thanks for your help anyway
Jack
