I think you need to show us the code you use to run the window.

It puts the runloop into a different mode, and blocks user events aimed at other windows, which sounds like what you want. Whether timers run depends on what runloop modes they were registered with; but there are plenty of other cases where modal windows are run, so the host app has probably had to deal with those before.
