Comment 3 for bug 1290045

We should probably decide what the expected behaviour is here. Re-reading this now, it sounds more like a useful feature than a bug to me.

If I open a construction site window and minimizes it, it's probably because I want to keep track of it and do something once it has finished. For instance I want to adjust the amount of wares or immediately upgrade a barbarian metalworks to an axfactory. In this case I get a notification that construction has finished, rather than having to un-/reminimizing the window from time to time to check manually.

We should probably discuss other possible use cases before deciding whether this should be fixed.
