Known Bugs & Fixes
White View ports
Click View >> Viewports >> Configure and choose a setup, then hit ok.
I can't select anything, and no menus come up when I right click!
Turn off anti-aliasing in your video card settings.
When I click on the Texture/Mesh browser nothing comes up!
Your desktop resolution may be set too low, and the menu is appearing just off screen. Temporarily raise your resolution and move the menu.
Every time I quit UnrealEd 3.0 it asks me if I want to save package0/ package1/ package1138. What do I do?
Always click NO. All the information you need for your custom map is saved within the map itself. Under the MyLevel package. Either way, messing with these packages runs the risk of messing up KF.
