Hi @citypaul ,
I have seen the Cursor team make reference to VPNs and zscaler before:
I wonder if you go to either of the following locations if you see any related error messages or logs:
Cursor > Help > Toggle Developer Tools and then click Console and see if there are any errors.
Cursor > Terminal and then click the drop-down and select Window (or any of the Cursor-specific options, such as Cursor Tab).
I am just a fellow user but hoping some of these steps will assist in troubleshooting.
