did you test on an android device or emulator?
if you used the emulator, test on a device.
if you tested on a device make sure you have always have a background bitmap even if its just a stage colored rectangle.
Thanks kglad. I've tested on an android device and I have a background bitmap as suggested. The bitmap is not covering the entire background on all the scenes. I will include this and see what happens. I do find the oddest things make a huge difference.
Thank you for your time replying.
