Hi, We are sorry you have encountered this problem.

Which extension are you using? Please make sure you have the most recent version of the extension. You can do this by clicking on the NetLogo Tools->Extension menu item and either clicking the Update All button or finding the extension using the scroll down menu on the left and updating it if it has a red icon. If the extension was not installed, click the install button (That should not happen because you should get a error message “Can’t find extension: extension-name” when you try to run the program) Let us know if that fixes your problem.

Otherwise we would like you to send us the model, or if it is complex, a simplified version that reproduces the problem. If you can make a version without sliders, choosers, switches and inputs, sending the contents of the Code tab would be fine. Otherwise please put your model in a zip file, or change the extension to .txt in order to work around a GitHub limitation.

Aaron
