Since the release of the update prior to my current version, the vertical scrolling behavior when moving up and down a data table has become very strange. I have never seen this in any other application. If I click and drag the scrollbar slider with the mouse and let go, scrolling *sometimes* continues. It starts fast at first and then slows down. I don't know what I am doing to make this happen and I haven't found a way to stop it once it has started. I just have to wait for it to stop. In a table with 500,000+ rows it is very annoying (I've had to wait up to 5 seconds).
