You are also using `system.tag.browse()` in the foreground. Like any other script function that calls out to the gateway, it should be called in a background script, and UI interaction handled with `.invokeLater()`. See this topic: > [@Update GUI via Asynchronous thread](https://forum.inductiveautomation.com/t/update-gui-via-asynchronous-thread/9666): > > I’ve got a script I am experimenting with that can take a lot of time to execute, so I now use the system.util.invokeAsynchronous to run the script in a separate thread to keep the GUI from locking up. I am using the asynchronous thread to copy files from one place to another, and I would like to show the progress of the file copy with a progress bar. How would I go about this? I am importing a few python libraries to do this. import shutil def fileTransfer(): path = system.file.openFile() … I make an exception for button actionPerformed scripts (short ones), as an operator can expect some processing delay upon their command. --- _[View the full topic](https://forum.inductiveautomation.com/t/designer-hanging-with-script-but-client-runs-fine/58006)._
