I have been doing maps and meshes for about a year now, and UnrealEd is not a friendly program. I have had to reinstall the game a few times and everytime I do I can't click on anything in the editors view ports. I can move around in the view ports fine but when I go to right click nothing happens and I can't click on any of the textures or anything, unless I use the shortcut to select all. Most of the time I hit every button on the keyboard and after a few days it will start to work again. It did work once and I was able to bring a mesh into the game but after that no luck. If anyone has had this problem or knows how to fix it please tell me.
