I came across this one.. I have a matrix in an undocked window on my 2nd monitor. This matrix has collapsed items that I want to expand from time to time as I am verifying calculations etc. When I right click on the collapsed items to expand them I get no “Expand” option. However if the window is docked the “Expand” option is visible. I am able to click on view –> expand all and get it to work. I would expect consistency in right-click menu options across the windows.
