Hello Group. I'm having an awful time with this. I have 2 essentially same codes using manipulate. Only differences are the ODEs. When I have both of the cells open, the Mathematica goes crazy, with the cell brackets flashing as if it's evaluating both cells at the same time. Eventually it will crash or I have to stop it using "Alt +." Is anyone else having the same problem? Here're the cells causing problems. cell 1 Manipulate[dsol=DSolve[{b''[t]==-k1 k2 b[t]-k1 b'[t], b[0]==b0, b'[0] ==bp0}, b[t], t]; Plot[Evaluate[b[t]/.dsol],{t, 0, 10},PlotRange-> All], {k1, 0.1, 10}, {k2, 0.1, 10}, {b0, 0.1, 10}, {bp0, 0.1, 10}] cell 2 Manipulate[dsol=DSolve[{k1 k2 b[t]==k1 b'[t]+b''[t], b[0]==b0, b'[0] ==bp0}, b[t], t]; Plot[Evaluate[b[t]/.dsol],{t, 0, 10},PlotRange-> All], {k1, 0.1, 10}, {k2, 0.1, 10}, {b0, 0.1, 10}, {bp0, 0.1, 10}] In two separate notebooks, these two cells cause no problems. In the same notebook, if one of the cells are closed (by double clicking on the cell bracket), they don't cause problems. It's only when the cells are both open, the mathematica goes crazy and crashes. Thanks for any info. Sean
