How can i move objects with arrow keys again

I adjust something wrong in the settings. When I am moving the object with the arrow keys the wireframe moves but the whole object stands. Dragging the object with the mouse works fine. Sorry for my bad english I am a newbie with this program ^^. My question is how can I solve that problem which settings I have to change or can change the settings to the factory status without reinstalling the program? The problem is only with BSP objects basic objects are working normal. Hope someone can help


If you translate/rotate/scale BSP Volume with the arrow keys, you must press Ctrl+Space for move object to BSP Volume.
