Buttons in dialogs does not respond on iPad.
To reproduce it: Go to Customer module, choose a customer and try to modify his seller. Try Cancal and Update buttons, they do not work.
This fail is because of flip effect on changing mode. So, until this fix would be fixes, you can fix it removing flip effect. To do so, just edit IPadStyle class and remove (or comment) the getCoreStartDecoration(), getCoreEndDecoration() and getSetHtmlFunction() methods.
This was produced by Flip effect. We solved this removed Flip effect, because this effect was also the cause of a serious performance problem.
