This is something I was hoping would have been fixed in the remastered edition of HW1&2: the camera problems when using a Wacom tablet. What happens is that the absolute mouse positioning on the tablet is incorrectly interpreted as a relative motion, which causes the camera to spin out of control. This has actually affected all older Relic RTS games.
After using a tablet for years, I’m no longer really comfortable with using a mouse - hence my hope for a fix. Also, if you’ve ever tried it, a tablet works really great for strategy games.
