I've been having this continueous problem with any scenebuilder (both Javafx and Gluon). Whenever I try to open a combobox or even the toolbar for Javafx scene builder the program Java just quits working and the program crashes. The same happens when I add a combobox to any java app and try to open it.
I need a scene builder because it makes making desktop apps that much easier and not even my profs at school seem to know what the problem is.
This screen shows what happens, whenever I open anything that drops down the program freezes and on clicking somewhere else it shows what should've opened all black. I know this is a Jfoenix menu but that is not the problem it doesn't work without jfoenix either.
Anything Java related is up to date and has been re-installed already.
