Is it possible to have a button JUST run custom javascript? I can get the code to fire ok (by putting 'javascript: mycode...' in the 1st field in the 'Link' tab) but buttons appear to always assume you are intending to perform a navigation action, and it is this I don't know how to supress.

(I could use a placeholder and output my own button html but then I'd loose the convenience of simply dropping one of Xara's nice button designs on the screen.)
