I am not sure I quite understand the behavior of the enable/disable option in the latest version.
Disabling works as I would expect it to... data flow stops from that component onwards and several components following the disabled component turn orange.
But when I enable a component which was previously disabled, the data flow does not seem to start, as in, the orange components do not turn gray again. I have also tried to "rebuild solution" but to no avail. The only thing that seems to work is if I shut down GH and Rhino and "reboot" the entire model.
Has anyone had better luck with enabling/disabling?
