What's your petty sewing machine rant?

I love my machine (Janome MC 6700P) but if I use the autosnippers, the top thread gets stuck down in the bobbin area too tightly for a piece of fabric to easily move it out of the way. I keep a pin or a pair of scissors at hand to sweep under the foot and scoop the thread out so I can fit my next piece easily under the foot. It's petty, because I'm grateful I have autosnippers at all, but I really wish she'd let that thread go more easily!

What does your machine do that doesn't have you thinking divorce but does make you huff and roll your eyes?
