Party Automatic Fold

Has anyone had an issue with being folded automatically? My hand history says it was an advanced option "fold" choice by me. My screen froze for a second or two and then folded my hand without me clicking on anything.

Party support of course thinks their software can do no wrong and insists it was my mistake. I had made a pre-flop raise with 2 callers. There was never another bet the rest of the hand and I was folded after the flop. Of course I would have hit a full house and the winning hand was A high!

I swear this has happened to me before.
