Actually, you probably won't be able to turn bumpmapping off at all, at least it shouldnt work with shaders on (That's an old client, bumpmapping might still have worked then).
But I dont fully understand, what do you exactly want to do?
Just to reaffirm what you are saying, you are correct, if 'Shaders' is ticked to off, then
None of the other options including bump mapping will be used regardless of weather they are on or off, it wont matter.
If the graphics are acting up I'd recommend downloading an updated graphics driver, if you inform us of your hardware, or go to your manufactures website, they or we can provided you with driver links.
