When you view your tasks in the Bar or Line view, the very last bar/line item on the right will not show up if you drag the scrollbar using the mouse.

1. Make sure you are using a mouse with a scroll wheel.
2. Also make sure you have a couple of task entries.
3. Switch to the Bar or Line view
4. Grab the scrollbar at the bottom with the mouse and drag it all the way to the right.
5. The very last bar/line item will not be visible, as if there was no entry, even thought the scrollbar is all the way to the right.
6. Once the scrollbar is all the way to the right, use the scroll wheel of the mouse and scroll it just a little (forwards or backwards, depending on your mouse preference settings) and now the last bar/line on the right will show up.
