Precision problem with matrix inversion

thanks Didier, this actually works, but inverting a matrix should also work by simply using the key combination "Shift ÷" (according to the Prime manual!) and in this case it gives the wrong result. Why should we tediously key in "inv(1)" if there is "Shift ÷" on the keyboard.

For me this seems actually to be a bug!
