I did search and perhaps I failed and it was reported before, but since I am playing 1.1 I might be someone who noticed this while others didn't.
Since I am eagre on not losing time between research, I switched on the reasearch popup and after some time noticed that the sound of the research completed (the all femiliar tundeedun) only sometimes plays after closing the research window when it popped up instead of while popping up.
The strangest thing, is that it doesn't do this always. about 50% of the time, the sound plays exactly when the window opens, the other 50% it plays after closing it (when pressing close or esc_.

Perhaps it was already known, otherwise I am happy I have been for once been able to help you guys with this one of a kind awesome game!
Have a good one
