Hi,
If you have physics for the object that you are turning 'on' then turn it 'off' it should work as you require it after that.
You can turn it off in the properties setting.
I don't know why its doing this, but it done the same for me as well the other day with the shooting target, in an example I was working on.
Hopefully someone can explain why.
