i got up this morning started up blender, pressed space to add an object no menu, i went to open up an old file no menu, i reinstalled 2.25 no menu’s, i installed an older version i got the menus but then the lower half of the screen is gone! and just 5 hours ago everything worked fine
that can’t be good, did you by chance download a virus? do the rst of your programs work?
It sounds like a driver/hardware (video card?) problem, if it worked then didn’t and reloading/installing the software doesn’t fix it… It may be a virus.
mcaffee and norton says all is fine ARRG!!
I just went thru everything i did for the past 24 hours and undid EVERYTHING, and low and behold the problem was solved!! My screen was set to true 32 bit color, i lowered it back to 16 and everything is back ! :o :o :o :o 
now dont laugh at me =(
we wouldn’t laugh, or at least not for long. glad everything is okay now.
amazing how the littlest things can mess up our whole world.
