The /reset command hangs after setting a startup script

[Robert Field]

Oh my!

/env -...

Sets the value, and then restarts. Part of restart is to run the start up 
script. So, yes, that creates an infinite loop.

Would someone not on vacation file this as a bug and post the bug number here.

Thanks,
Robert
