Mathematica 7 uses Java 6. Do use a different context for your two notebooks (when things work OK). The problem is that your variable dsol is shared by the two calculations - so one changes its value, which triggers the other into action..... I solved it my using a Module to localise dsol: Manipulate[ Module[{dsol}, 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}] David Bailey http://www.dbaileyconsultancy.co.uk
