I can tell you I've fought the same battle and finally built an ON 
EVENT FN to handle mouse button down events before the runtime. Here is 
a partial listing of some code to give you the idea.

It basically looks like:
local FN doEvent
dim ev as ^EventRecord
dim as int i, oldWind, day
dim as WindowRef @ evntWnd, wNum
dim as rect        btnRect
dim as point       mousePt
dim as short       whatPart
dim as str63       ef,buttoncontent
dim as long topItem,lineSelected

ev = event
select ev.what

'case _nullEvt


case _mButDwnEvt
wNum = mouse(_mouseWindow)
select wNum
case _MyWnd

mousePt = ev.where
GlobalToLocal(mousePt)

fn FBGetControlRect(button&(_aStaticEditField), btnRect)
long if fn PtInRect(mousePt, btnRect)
fn doSomething
ev.what = _nullEvt'tells FB runtime not to do anything with this
exit fn
end if
