On Error Resume Next is actually weirder than an empty error handler. If Python errors halfway through a try/except block, it will skip the rest of the block. If you On Error Resume Next, VB will literally just proceed to the next line and keep executing. And since you don't need to indent the block that comes after On Error, it's easy to miss that line...
