Hello Rush,Hello, Jameskkli...
Welcome aboard. There might be a rogue or incompatible installed application causing this problem. Have you recently installed any app? If so, uninstall and see if the problem persist.
Also, just as El Presidente said, clearing data from the application sometimes fixes this issue.
Best of luck. :ciao:
Yes, I did follow that route for cache cleaning but not a positive return,thanks anyway,Hi James, welcome to AF!
Have you tried clearing the cache and data of the app via Settings -> Apps -> 3D Photo Browser?
Alternatively, head to the Acer 500 section and I'm sure the guys there will be able to assist: Acer Iconia Tab A500 - Android Forums
