It appears the Solve and O[x] don't mix. Consider the following.
Mathematica 2.0 for NeXT

In[1]:= Solve[x+z==1,x]
Out[1]= {{x -> 1 - z}}
In[2]:= Solve[x+z==1+O[z],x]
Out[2]= {{x -> 1}} (* I would prefer x -> 1 + O[z] *)
In[3]:= Solve[x+z==1+O[z]^2,x]
Out[3]= {} (* What is wrong with x -> 1 + z + O[z]^2 ??? *)
