Managing the hilite color of selected text

[Pete]

Thanks Terry, I pretty much have that logic in there now.  My remaining
problem is dealing with the tab key which I documented in another post on
this thread.

Is it just me or does seem like a lot of work to implement a pretty standard
user interface issue?  LC appears to remember the insertion point position
of a text field when you leave it so why not the selected text?
