Hi,
Currently, if you drill down through several layers of modules and try to open the menu of a module to open the source module it appears as if the menu has not opened.
I have learned from experience that the menu does actually appear, but seemingly in a random position further up from the drill down tabs, and floats as you scroll up and down.
I have spoken to colleagues about this and some have even assumed that opening the menu simply did not work from a drill down menu because of this behaviour!
As far as I am aware, this behaviour has existed for a very long time - please resolve!
