Using Pretty with R2011a?

I have R12.1, R2011a and b in the Windows 7 environment. I do not use R2011b because it has a problem with soundsc. When I use the pretty command in the symbolic toolbox with R2011a the display is all out of whack and is basically useless. I have to use R12.1 (Matlab 6.1) with pretty if I want something intelligible. Has anyone else noticed this problem with R2011a?

Thanks.

Hmm, is definitely not related to R2011b, I have checked the following on all Ver R2010a,b, R 2011a,b and R 2012a on both windows 7 and MAC and the outputs are all clear correct. Might have some problem in the MATLAB installation. I would suggest contacting support..

FYI the following output is directly from Win 7 R2011b (All others were identical)

>> A = sym(pascal(2))
B = eig(A)
pretty(B)

A =

[ 1, 1]
[ 1, 2]

B =

   3/2 - 5^(1/2)/2
   5^(1/2)/2 + 3/2

    +-            -+ 
    |         1/2  | 
    |        5     | 
    |  3/2 - ----  | 
    |         2    | 
    |              | 
    |   1/2        | 
    |  5           | 
    |  ---- + 3/2  | 
    |   2          | 
    +-            -+
