What happened to system.net.openURL? I just updated one of my projects from 8.1 to 8.3 and my scripts that use this are acting different. I went to see what the manual said about it and it's gone, but not shown on the Deprecated list.

I use it to open a saved file with it's default program in Windows, but now it just opens a web browser and downloads the file.

That call is entirely dependent on the file associations already in the computer.

`system.net.openURL` got moved to `system.vision.openUrl` (because it's a function that can only possibly make sense to execute from a Vision client).

The actual implementation of the underlying function hasn't changed since 2015.

system.vision.openUrl didn't work... but

system.vision.openURL did 🙂 .

Exactly what I needed. Yes, I only use this in a vision client
