NetLogo-Mathematica Link's NLStart

[chris]

Here is a small unexpected aspect of the NetLogo-Mathematica Link. There's also an easy workaround, but it's surprising that when starting the link with …

<<NetLogo`

NLStart["/Applications/NetLogo 6.0.4"]

and (eventually) finishing with

NLQuit[]

but keeping the current Mathematica kernel running, and starting up the link again with an intended different version of NetLogo, like this

<<NetLogo`

NLStart["/Applications/NetLogo 6.0.1"]

the actual NetLogo version usage doesn't change. The 6.0.4 version still boots. The workaround is to quit the Mathematica kernel before using <<NetLogo` again.
