Managing the hilite color of selected text

Thanks Craig and Dave - I used Dave's suggestion (mainly because I'm not
very familiar with using graphics in LC) and all seems to be working fine
now.

The only remaining issue I have now is how to figure out if I entered the
field via a mouse click or a tab key.  Right now I have a tabKey handler in
the control whose layer is 1 less than the layer of my text field.  In it, I
set a custom property of the text field to indicate that I entered it via
the tab key and check for that in the openField handler of the text field.

For some reason, pressing tab in the control whose layer is 1 less than the
text field doesn't give focus to the text field.  It's traversalOn property
is true and lockText is false.  Any other reasons why I can't tab to it?  Or
maybe there's a better way to deal with this situation?

Thanks,


Pete
