compile button on tool bar

List,

There is a button on the tool bar whose tool tip is "compile the current 
source using the last used compile command". I would really like to use this 
but it is inoperable when working in the iSeries Project perspective.

From the Projects perspective you can point to a source, right-click and 

choose Remote Actions->Select Compile Command which I assume is to be used 
by the button yet the button won't work. Why is that?
