Hi Dan,
unfortunately, Win32Lib always assumes that modal windows are visible. I can
achieve what you want for a non-modal window

----------------------------
object VOID

  openWindow(myWin, #08000000)  --a kludge to open it "hidden"

  VOID = c_func( xShowWindow, { getHandle(myWin), SW_SHOWNORMAL } ) -- to
view it.

  VOID = c_func( xShowWindow, { getHandle(myWin), SW_HIDE } ) -- to hide it
again.

-- This only works in 0.53 because getHandle is global from that version.

----------------------------

A number of changes will have to occur to allow initially hidden modal
windows. The main one being that modal windows, by definition always have
focus; but if its hidden, it shouldn't have focus.

Currently, Win32lib always makes sure that the latest open modal window
always has effective focus. It wouldn't be very friendly to have a hidden
window that has the focus!

I think this is so, but maybe David or Matt can confirm or deny.
