I just tried it on a different computer with a different operating system and I beat the level first try. Everything worked the way it should have. Not sure why it works differently on different OSs, but there you have it. FYI, the computer that worked is running Windows 8, not working on Windows 10.
Re: level 4372. For many people, the cherries do not pass through the exit once the spawners are destroyed, but pass over onto the right side instead, where there is no exit. This has been an ongoing glitch (according to the posts here) for some time. Any chance it will get fixed? The level is impassable without a fix.
