I suppose the question that this error is asking you is: when `getWindowAttributes` throws an error, how should `floatLocation` respond?

Yeah, and I don't really know enough to answer that question either. I guess something is really wrong with the window, and XMonad should give up?

I am not sure I understand wjy getWindowAttributes would throw an exception except for "window removed",

That could very well be it, I usually see the exceptions from getWindowAttributes in floatLocation when Gimp opens windows that display some kind of progress and quickly closes them again.

and for most of those you probably want to be aborting the hook in question. So, make sure it's always under control of userCode; this would include moving the one in X.O.manage into a userCode, but that would probably be smart anyway since I think we crash currently if the new window we want to manage goes away before we can. Or both its uses (one to manage initial windows at startup and one in response to MapRequestEvent).

Yes. Uhm. Ah. I haven't got the foggiest of how to do any of that. Best regards, Adam -- "Good evening. Today is Good Friday. There is no news." Adam Sjøgren asjo@koldfront.dk
