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?
