I would like to play A.WAV at frame 1, and then B.WAV at frame 150. However, when I insert the 2nd play sound B.WAV action, it changes the first action to B.WAV (It was A.WAV). And if I change the first one back to A.WAV, the 2nd one also gets changed to A.WAV!

Am I doing something wrong, or is there a bug, or am I simply not able to insert two such actions within one scene?

Thanks.
