Clipboard Manager v5.2

I double-click the ClipMan icon in my TLB taskbar, and there's no deletion of the clipboard history.

If the clipboard manager is on the toolbar then you have to enable double clicks here: TLB Settings->Toolbar->General. Turn off the option "Disable double-click for toolbar buttons"

Yuri how often will the Clipboard manager check to see how old the clips are in the clipboard manager and when they are removed?

Once per 1 minute.

unchecking "Disable double-click for toolbar buttons" worked and I can now double left click to clear clipboard. However for some reason I can not get the middle wheel click to clear the clipboard.
