[Xymon] Windows PS xymonclient

Hi Paul,

Like I said to Zak in a one-to-one e-mail last week, I think this is a
Windows issue, not a client issue exactly, although it would be handy if
the client log showed an error and what the error was.

Do the new versions work fine in a Administrative powershell prompt if you
run it manually from there?  Or do you get any errors related to these
empty sections?

Kind regards,

SebA
