Hello,
I have a problem with my new Intuos 4.
I found the similar thread on the fotum, but the problem was with Intuos 3, so I decided to put it in a new thread.

When i draw diagonal lines with tilted pen they are very weavy. When the pen is pointing straight down it draws straight lines. I asked about it on the official Wacom forum and got the answer that it can be "to some extend" caused by the driver which should be improved and ther's no fix for it, but that doesn't convince me. I bought the Intuos 4 for the precision and what I get is...



The tablet was tested on the latest driver with Mac and PC (Win 7) and with Photoshop, Sketchbook Pro, Corel Painter with the same results.
I visited the Wacom store and was told that the lines should be straight even with tilted pen...

So...
PLEASE
if you have Intuos 4, take a ruler and check if your diagonal lines with tilted pen turn out the same way...

...if yes - than in my opinion this tablet sucks. This is a huge disadventage.

...if no - than i will be very happy and will send my tablet across the world to be exchanged.
