I started using my X60T as creative device, and found that by default, Manga Studio EX4 does not recognitize the Tablet PC digitizer. So I went to Wacom web site, download the driver (ISD_DualTouch_701-8.exe). Once I was done, I tried Manga Studio EX4, found that same problem still existed. But after I brought up the "ISD Tablet Properties", the problem went away, and continue to work properly with touch sensitivity even after I closed the property window. I have to do the same trick everytime I start Manga Studio EX4 from scrtach, but I am good as long as I found the pattern.
