Call the project script with [invokeAsynchronous()](https://docs.inductiveautomation.com/display/DOC79/system.util.invokeAsynchronous). Within the script, you can write to tags, but don’t access any windows or components in any way. If you must, use [invokeLater()](https://docs.inductiveautomation.com/display/DOC79/system.util.invokeLater) to spawn functions that can interact with the GUI. Consider using something like later.py, as described in [this thread](http://forum.inductiveautomation.com/t/update-gui-via-asynchronous-thread/9666/2), to help with sending data back and forth with these functions.
