Help Scrolling the screen in my g tablet

[cub2000]

I don't think this has anything to do with my rooting the g tablet, so I post in this forum instead of the rooting area.

When I scroll the screen of long list of apps that I have, it would open an app where my thumb is, that I don't intend to open. This is not the case for my HTC phone. Can someone please give me some tips on scrolling the screen on the g tablet so that it doesn't accidentally open an app?

Thanks in advance.
