I can't see the text in layout

[Cesar]

Hello to everyone.

 

My problem is, when i put text in the drawing, i can saw very well in the model window, but when i move to layout window disapears, is strange, i start to zoom out, and some black blocks stars to appears, like when you saw the text far away, i zoom in, and desapears again.

 

Someone can help me with this issue, because is very annoying, i work with autocad 2007, and i have this problem running the program inside a dell, and inside a mac throught boot camp, so i dont think is video card problem. also doesn't affect the prints.
