    I purchased the wonder media WM 8650. I can't get it to operate in a timely manner. Is there something I can do to speed it up? I tried to log into this site using the wonder media tablet and it's still in the process of connecting. I've tried my wireless network, it connects and is really slow, I am currently using an Ethernet connection and it's no faster. I've been able to sign up for this site, (using my laptop) I've set up user name and ID so that I can ask some of these questions and the wonder media WM8650 is still not connected. It appears that it's in the process of. I have been able to load my Google account with email and links. Is it that I bought a worthless piece of equipment or is there something I can do to make use of this product worth while? I would appreciate any advice you can provide. Thank you.

    @netseeder, What you have been doing with the editing is way beyond my skill set, but it appears to me that you are using ROMs that were not intended for an 8" tablet which is why you are getting the split screen. I would try changer.bat versions 3-6, 10, 15, 17, 35, 40-43, 55, 62, 76, 77, 80, 85, 96, 101, 108, or 117. If everything works but the touchscreen, go to the Techknow forums and search there as I know they have some fixes for that problem.
