Can't VIS a simple Verilog

Hi,

I ran vl2mv on the attached Verilog and got a valid mv file.
Now in VIS, running flatten hierarchy or init_verify gives
me the following errors...

[ 48 ] design1 -: vis
vis release 2.0 (compiled 27-Sep-03 at 6:43 PM)
vis> read_blif_mv design1.mv
vis> init_verify
Table _n363<0> is not deterministic
Table _n363<1> is not deterministic
Table _n363<2> is not deterministic
Table _n363<3> is not deterministic
Table _n363<4> is not deterministic
Table _n363<5> is not deterministic
Table _n363<6> is not deterministic
Table _n363<7> is not deterministic
Table _n363<8> is not deterministic
Table _n363<9> is not deterministic
Table _n363<10> is not deterministic
Table _n363<11> is not deterministic
Table _n363<12> is not deterministic
Table _n363<13> is not deterministic
Table _n363<14> is not deterministic
Table _n369<0> is not deterministic
Table _n369<1> is not deterministic
...
etc.

Does anyone understand the reason behind this?

Thanks in advance,
