Unreal launcher issues

am I the only one that has issues with going to the marketplace through the launcher? Sometimes it don’t go at all , just black screen, but nearly everytime I look at something on the marketplace , I try then to go look at something else and it wont go to it, it keeps going back to the last thing I looked at, will not go to the next one. Even now I was looking art an alien , go on to look at a zombie and when I click on zombie , it keeps going back to the alien.
