Play-back bug

This happens quite a few times, but I'll go back to listen to a section of music with playback, and when I click to stop it, the last note I was on holds it's pitch. If I re-enter playback, the pitch continues to be held while the music goes on, creating a lot of ugly sounds. The only way I've found to stop the never-ending pitch is to close down musescore and open the project back up. I haven't been able to recreate it (seeing if it occurs for certain notes/types of notes, with accidentals, or in the middle or at the end of what you have written), but it occurs very infrequenty. It's not a detrimental problem, but it can be quite annoying to have to close out of the program and open it back up again. I'm not sure if it has to do with a part of the code or something wrong with download onto my laptop.
