Happy to help. I know how you feel about the aggravation. My installation of Illustrator simply doesn't work with either of the Wacom driver updates released in January. I wouldn't get much farther than opening a layout and making a few changes before the application window would hang and disappear. Wacom released a newer driver for the OSX platform. I'm wondering how that one is faring compared to the Windows drivers.
Hello ! Back for a good news for Windows Users : Today Wacom release the 6.4.2-1 Driver and referring to the release notes, it's fix the crash when using Adobe Illustrator, Corel Painter, or Autodesk Maya.
I just made the update and it seems to work perfectly now ! I don't have any Illustrator crashing as before with the previous driver (version 6.4.1-3). Great news !
