Your one experience totally invalidated the huge list of people who have issues. Clearly if they just tried something as simple as re-installing (which only you are smart enough to think of) everything would be fine for them. It can't possibly be that you got lucky and a simple fix managed to remove your issues, but others with a different PC set-up have a completely different set of bugs that will not go away with your simple fix. Thank you for this worthless anecdotal evidence that clearly invalidates anyone elses experience.
