A known bug that has been fixed. The function called fDoNM_RCLICK needs to be as
below...
----------------------------------------------------
function fDoNM_RCLICK(integer id, atom hWnd, atom wParam, atom lParam)
----------------------------------------------------
sequence xy
atom keys
integer lRealId
lRealId = W32_fetch( lParam, NMHDR_idFrom )
if lRealId != 0 then
lRealId = getId( W32_fetch( lParam, NMHDR_hwndFrom ) )
else
lRealId = id
end if
xy = getPointerRelPos(lRealId)
keys = getKeyMasks(0)
VOID = invokeHandler( lRealId, w32HMouse, {WM_RBUTTONUP, xy[1],xy[2], keys}
)
return {kReturnNow}
end function
and the routine 'getPointerRelPos' should be ...
global function getPointerRelPos(integer pId)
if validId(pId) then
return getPointerPos() - ClientToScreen(pId, 0, 0)
else
return {0,0}
end if
end function

Oooops! I just copied the code from the unreleased win32lib. Just use fetch()
instead of W32_fetch().
All the functions that used to be in the toolkit libraries have been renamed
with the prefix "W32_" and now stored in a single win32lib specific sub-library
(w32support.e). I will be providing a conversion library in case anyone actually
used any of the toolkit names.
This was done on advice that my old identifer names were too likely to clash
with other peoples' identifier names and it really was my responsibility to
prevent that. Any talk of namespace facility was not taken well. I assume they
are right.
Sorry for the inconvenience.
