So, recently Iv'e been trying out Macromedia Flash (because you can get it for free) with my digital tablet. So... the problem is that when I zoom in, most of the time, it doesn't draw but it moves the screen (sorry for some broken English). Here's a video: https://www.youtube.com/watch?v=iig3veNk_3I
Something else I just thought of, was if you are trying to display on another screen, the tablet will only have its native resolution to display, so you may be dealing with "dueling" screen resolutions. Just a thought and no proof!
