I just discovered that if you have an error box open when you update a Vision Client, the client can end up soft-locked. The update popup is modal, but the error box retains visual focus. If you’ve resized the error box to read the stack trace, you can cover all interactable parts of the update box. Only way to fix the issue is to end the client’s task in task manager, as far as I can tell.
I presume this also affects message/warning boxes, but I haven’t tested it.
