This has perplexed me for sometime, and I could never find a solution on the web when I searched, so thought I should post this here to help any others who are caught by this as well.
When you are editing a widget, there is a SN menu that you access by clicking "Control-Click" (or "Control-Right-Click" depending on which browser you are using). You then select your choice and it launches that choice - but it never worked for me.
I finally discovered what the problem is. - When you control-click to get the menu to appear, LET GO of the "Control" key FIRST and THEN click the menu item! - If you continue to hold the "Control" key, nothing will happen when you click the menu item.
