model/card that disappears

[x11start]

on the bottom bar of autocad 2010, I always miss the model writing (or paper) that allows me to pass from one state to another.
It is true that just click on it with the right mouse button, choose the drop-down menu to make it recomparite.... but how do you save it so that it does not disappear anymore?

I'm not sure, but try to save the work area with the displayed button?

Of course I tried... It's all right.
If at least I can figure out what's the thing that makes him disappear...
as I say it is not a great harm, as it is restored immediately with the right mouse button .... but it's a nuisance!
