For some reason, the thumb portion of my scroll bar is hard to grab. One needs to click and grab very directly on top of it, otherwise you cannot select it. Is there a particular size the thumb needs to be?
The "clickable" area of a control normally matches the pixels of your artwork exactly. So, if your artwork is tiny or very thin, it will be harder to click on. If you want a larger area to be clickable despite the small artwork, here's one trick:
This will create an invisible "mouse hit area" within the thumb to make it easier to click
Hope that helps!
Thank you. Great solution.
