Hah! I can relate to the folding test stand going for walkies.
Twice now I have had a PAW 40 drag my portable folding work stand across the polished concrete garage floor - normally wouldn't be an issue if I kept an eye on it but the first time it happened I turned my back on it for a few seconds only to have it 'chase' me.
When the same stand is placed on grass it does indeed want to flip over and resting my foot on the rear of it pins it nicely.
Cheers.
