My pop up menu deselects my text...

[m]

I am trying to create a context pop up menu that allows you to simply
copy text.  
 
Problem:  the “popup” command works just fine, but as soon as my menu
pops up, my selected text is deselected.
 
I have a goofy work around right now where I just throw the selected
text into a container and then change it’s color (so you know what was
highlighted) before popping up the context menu.
 
But I need to be able to pop up the menu while keeping my text selected
(like all word processors do).
 
What am I missing?
