Im using Actiontiles and Fully kiosk browser, and Im having this issue that some times the sceens goes black. I can acces Fully and load another URL. But when I reload Actiontiles the screen is still black. To cure the problem, I have to Clear the cache in Fully, then I have to reenter password etc, and every thing is fine. It's like the web app crashes some times. Has anyone else had this issue?
