How to minimize all windows (and not have them pop back up by themselves)?

Hi All, Both the ‘Show Desktop’ button and Ctrl+Alt+D will minimize all windows and upon repeat action raise just those prior minimized windows. All good, except; A) It seems locking the session also raises the windows again and B) raising anything prior to re-clicking ‘Show Desktop’ resets the ‘Show Desktop’ action so it doesn’t now raise just those prior minimized windows. Replication: A) Ctrl+Alt+D {windows are minimized} Lock Session Login {windows have been restored} B) Ctrl+Alt+D {windows are minimized} Click a task in the taskbar (e.g. Firefox) Ctrl+Alt+D {window is minimized} {prior windows are not restored} Anyone know of a way to minimize all displayed windows such that A) results in windows staying minimized upon lock/unlock and in B) (re)performing the action (or even using some other command) results in the original minimized windows being restored? Possibly something using dcop kdesktop ??? , maybe dcop twin ??? (I tried looking there, but even using kdcop, it’s like finding a needle in a haystack for things even relevant) Thanks, Michael PS: Way to go whoever is doing TDE SEO, Google search on “dcop gui” returns https://wiki.trinitydesktop.org/Tips_And_Tricks in 5th place :)
