Thanks for the replies. I have version 4.30.16
None of the above suggestions work for me, probably my lack of understanding of this new TV :-)
I assume I should be using the Magic remote?
If I hover over the app it pops up slightly. To drag I guess I press and hold the wheel? Nothing happens when I do this.
If I highlight the app and press the up arrow, selection of the app is lost and the pointer moves to the Inputs icon at the top of the screen.
I have ver 4 software, where should the option "x" to remove show up?
I appreciate all your help, would love to get this sorted out.
