Thanks for your time.
Plain $ZF(-1) and $ZF(-2) calls from Cache Studio or Terminal have stopped launching the OS shell from Win10.
cmd (Windows Command Prompt) should be launched.
Windows 10 Anniversary Update, Ensemble 2016.2.0.585.0 Developer Edition x64
Is this common? I have enabled both %Developer role and a Cache CallOut privilege for all users that operate in this scenario.
In Terminal, W $ZF(-1) prints -1, W $ZF(-2) prints -1
In Studio, W $ZF(-1) hangs the IDE, W $ZF(-2) prints 0
