gris problem
 

just woke but while im here.., im working in feet, i have all preferences in feet.., but it wants to default to centimeters.., while remaining in feet.., so i get a grid thats very small when i open the scene.., at times i open it and it has decided to change the preferences to show numbers??

here are examples

this morning i opened the scene twice.., first small with no numbers

then i opened it again (after fixing the problem.., if thats what t is??) and it has decided i need numbers??

ive never had this much problem with any app.., im starting to wonder if the graphics driver was meant for vista???
