I just ran the exe on my machine and did have the same problem. The oildrums are not seen falling over unless you pull back the controller quickly, but they should be falling forward away from the controller.
Some people may not see this as a problem but I do. As I said before a clean re update solved the problem for me after weeks of altering values to no avail.
EDIT: I have run your example several times and sometimes it works fine and sometimes not. Strange.
