There are some examples of windows in examples.. Under Linux, the SWI alarms work well, but under Windows they have problems. If you try SWI windows for 5 minutes and see that they don't work under Window, please try to ask the SWI mailing list (Jan Wielemaker) and see what he says.
ETALIS windows are built on top of these alarms, so sometimes they create problems. We are looking into other alternatives too.
