Dear Matthew, further to my last email I have down loaded the latest demo

  and this exhibits the same fault. e.g. if you draw say a single line. 
Then with it unselected try and select it again with a single click over 
the item, it is not selectable in RPCemu, but works fine on A5000, RPC. 
ProCAD is quite fast and i wonder if the selection routine is different to 
normal systems. However, selecting with dragging a square works fine.

  I will continue to investigate, but any thoughts welcome
