This is a function of the "error" messages that I've been griping about that
don't really do much except clutter up the screen. At least they are less
frequent now.

This works for me. Want to update all and check again?

This is fixed

I can't duplicate and so don't know what the problem is here.

I've made this a bit easier. The buttons change to cancel/apply/OK for
display command options windows. Simply pressing return (OK) will save the
options and close the window; pressing "apply" will save the options and
leave the window open.
