Problem with DSolve


can anyone help what is wrong?
On version 7 I enter

   DSolve[{y'[x]==.02*y[x]-y[x]^2,y[0]==a},y[x],x]

and get

       During evaluation of In[58]:= Solve::ifun: Inverse functions are being used by Solve, so some solutions may not be  found; use Reduce for complete solution information. >>
