I am on Windows 7 and use Hydrogen 0.9.6 preview release for windows.
I am trying to make a whole new library with 13 sounds, and I am doing this by changing the layers in one already existing drumkit. Unfortunately I never finishes and saves the whole library because suddenly when I close the layer-editor Hydrogen stops. Windows then gives me the message that the program isn't responding and I have to shut the program down.
I have tried to close and open the layer-editor many times and fast, but when I have nothing to lose it don't crashes.
An other program that I also use originally made for Linux sometimes does the same thing after a while (Rawtherapee). However it have done that both in Linux and Windows and on a different pc.
