* This bit of code below sets the functionality of the Next Problem button. It starts off with hiding this window,
* so as to more seamlessly transition. Then it creates a new form of the next problem in the book, and shows it.
* The reason I used ShowDialog, as opposed to just Show is that I wanted to switch over to the next problem with
* no remnants of the previous so it can be properly closed, and using ShowDialog shows the new form modally
* (making it so directly returning to the previous form [so... THIS form] is impossible), as opposed to Show's
* nonmodal format. Using Show makes it so the next line of code that is supposed to just close this form instead
* closes all forms. Still not 100% certain why, but yeah, that happens.
