This isn't world breaking, but it's always been an annoyance.
Add a Button, and then set it up to be Checkbox, with text and all.
Whenever you click the checkbox at runtime, it goes bold. Why?
Then it stays bold, until you remove the mouse.
This looks really odd and breaks windows convention. Other programs' checkboxes do not do this. If this is a feature somebody wanted, please add a way to disable it.
As it stands, I have to make a checkbox without text, and then put a String object next to it.
But then I have to do more work to make the string clickable, like the text of a checkbox is.
So yeah, please fix the weird bolding of the checkbox text on click.
