Opening multiple javaviz instances #98

Closed drasmuss closed 10 years ago

drasmuss commented 10 years ago

Opening multiple instances of javaviz breaks things (seems like data is not making its way to javaviz). Closing all the open instances does not fix it, but it is fixed by restarting nengo_gui (it is not necessary to restart the javaviz server). Ideally we would support multiple instances, but I don't think that's critical. A more immediate fix would be to prevent the user from opening a new javaviz instance if one is already open.

?? Weird.. it's supposed to work fine with multiple instances....

Multiple instances works fine for me... what error messages are you getting?

Don't forget he's on firefox...

I believe this is the error that's breaking things:

Unhandled exception in thread started by
