Suspend Guest button disabled in Player 5.0.1

Hi,

I recently upgraded player 4 to 5.0.1 build-894247

and I cannot suspend any of my VMs anymore.

I have several Windows and Linux VMs, some with Tools,

but most without,

and all of them used to suspend OK in the old player,

but the new player has all "Suspend Guest" buttons and menu items

disabled (grayed out). Only Shutdown Guest and Restart Guest are available.

Why is that?

Thank you
