Pointer shape fluctuates when it should be displaying the hand (ie touchable item)

[Alan Glover]

When the hand mouse pointer should be displayed to indicate an item is touchable the pointer does show the hand but several times a second it very briefly flickers back to the standard arrow pointer resulting in a distracting effect on the screen all the time the pointer's over something touchable
