In this project, you can click on the slider black button to move it along the black line. If you release the mouse button out of the textbox element, the slider-button is unselected.
Unfortunately, when you release the mouse button over the textbox, the slider button remains selected. And this results in a clumsy interface. How to solve this?
Perhaps you can add another condition to the events?
I've tried to do so, but the bug remains...
