I am using a Samsung Windows 8 700T1C tablet PC which has a WACOM digitized screen.
When I use Photo and Graphic Designer 9, I can use my digitizer pen to select tools and menu items, but when I try to use it to draw ing
the freehand tool, the pencil icon appears on the screen but no lines appear !

All the other apps I have, such as Inkscape work fine. I have pressure sensivity enabled.
Drawing with the mouse works fine.

Is there a setting I am missing ? Is anyone else having a similar issue ??

Thanks in advance.
