accidentally double clicked on an ant in the config page and got an unhandled exception, clicking continue it seemed to continue to work fine.
Looks like if you remove ants from config it will only display properly next time you start the program.
Might be nice to have in the right click menu on the ants page to have option to goto antminer webpage.
What's really odd is that I just started getting the unhandled exception now where it was fine before.
