Another idea is simply to take a screenshot of the actual interface you are working with and using a graphics package, simply cut out the button remebering to make a "pink or bright green" background around it a pixle or so in thickness. ( I use either colour because they are usually the two colours furthest away from the normal range - thus, easier to define and make transparent ).
Then, you simply import that picture on an Opus button and ask for the background " pink or green " - to be transparent and the button pic to be shown in full size.
You should be left with what looks like an exact replica of your original button - and by adding a mouse over, your border will be more clearly defined by the transparent "edge" around it.
Hope this helps...
P.S...
The PINK in " windows paint " application seems to work really well for this task.
