At times I'll have 3+ Logos windows open (e.g. main screen, library, floating window for reading, ...). If I've got all but one minimized and then I close that one non-minimized window, one of the other minimized windows restores (typically the main screen).
Stop that! I've got my windows minimized for a reason. When the other window restores, it is in the foreground and thus blocks me from directly using another window/application I may have wanted to get to. It's not quite as annoying as web sites that change the size of my primary browser window, but almost... 
In case it matters - this is Windows 7 Ultimate x64.
