Who Raised: Kris Singh
Description: By clicking the Play Notes button multiple times, whether it was an accidental double click, or intentionally clicking it many times, queues the playback for as many times as it is pressed. i.e., if the button is pressed 5 times, it will playback 5 times without stopping. This is an even greater issue since you cannot click on or close the window while it is playing, meaning it is very easy for this to endlessly loop on a client's computer and be uncloseable. I decided not to bring up the not being able to do anything during playback bug since there are already 2 reports on it.
Version: Master branch as of March 23rd, 2022
Platform: Windows | Eclipse
Reproduction: Enter any valid tablature, then click on Preview Sheet Music. Then, click on the Play Notes button several times to reproduce the bug.
Expected: The application should only play the sheet music once, any further inputs should be ignored until the current playback is finished, unless a play/pause feature is added.
Actual: The application queues up a playback each time the button is pressed without a way to remove the queued playbacks.
Priority: 5/5
Severity: 5/5
