9 years ago Good test case! I just tested, and this issue is not handled correctly in the Java version, so it is likely a problem that has always existed and just got ported with the Java code. This one may be tricky.

8 years ago The issue here is that the step back button is enabled in some cases when there is no data to step back to. Clearing the chart also clears the recorded data, so once cleared, stepping backwards has unintended consequences. This bug was apparently present in the Java sim, but was just never caught. I've changed the code that enables/disables the step back button so that step back is disallowed when there is no recorded data. This appears to fix the issue, but I'm leaving it open until #92 is also resolved, since they may be related.

If you pause the simulation while the Neuron begins to be stimulated, then Clear the Potential Chart weird behavior occurs after rewinding. (Pause around this point of the Stimulating Neuron process)
On Safari 9 and Chrome and Firefox Hitting rewind multiple times after this point will not draw the "ring" moving in reverse up the neuron. Instead after rewinding it will constantly generate Sodium ions moving out, Potassium ions entering, and even disappear. Hitting play afterwards will re stimulate the neuron w/o ring and Potential Chart will not be drawn with vertical bar.
Extra weirdness: This Freezes the Simulation on Safari 9 OS X 10.11 and Firefox 41.01 Win 7 On Firefox debugger brings attention to Line 464
