2.63 has been running fine.
today all the faces of things i made over the last few weeks have vanished!
the standard file with a cube is okay.
i tried several of the files i recently made and they are the same.
all i can see is the extrude things that i did not convert to mesh.
can the videocard do this?
i tried the file on another computer and the faces were still gone.
so i tried on the first computer to edit select all F. and it made faces but it keeps crashing after about each one.
i doubt if updating to the current version will fix this.
PS the menu print is smaller so it looks like the settings have changed in blender
included is a drastically cut down version of the blend file
