When I start TV on my media portal client, it starts well and when I do change the channel it changes, but it will stop responding to my commands using keyboard or remote, and even with the mouse it appears on screen, but media portal is not displaying the control buttons on the top of the screen. this issue I have noticed on v1.4 and I thought it will be solved by v1.5, but it isn't. I'm sorry that I didn't report earlier.
