When inventor is running slow and you try to access the "I PRO (File)" button at the top left corner to access commands - even though you wait a couple of seconds between clicks, it registers as a double-click and closes Inventor. (I have lost count of how many times this has happened).
Where do you turn this feature off? You should have to turn it on, not off. I never use this feature, I always use the big red "X" in the top right corner.
Thanks
