It's not hostile, so much as pointed. Any person coming to these forums, who has had a passing interest in KSP, might be put off by seeing such threads, when in actual fact that are many satified users. Flightmaster IS running a modified environment. All bets are off. If Flightmaster a) Completely, cleanly, uninstalls the game (by actually deleting any remnants of any part of the game after uninstalling) Installs a fresh copy of the latest version c) Ensures his machines drivers are up to date d) does NOT install any modifications WHATSOEVER ...and continues to exhibit problems, then by all means we can talk. Until then, he is the hostile one, making claims for which he has no proof. All he has proof of his that his copy of the game isn't working, not that there is something inherently wrong with .20.
