Resolve issue with copying a word in PI Output Enhancement Viewer

In the PIOE Viewer only the first letter is copied, when Ctrl + Shift + Right arrow is used to select a word and copy it.

ListEditor.java - when shift and control are both down and arrows are clicked, get the last position by invoking later as the caretUpdate is delayed.

Fixed code in the MGR3.0 release.
