Hello mlk1968p,
I'd suggest clearing your browser's cache or try if it works with a different browser
like Firefox, Microsoft Edge or Google Chrome, for example. 

If this does not solve the issue and you are using a smartphone or tablet,
could there be a problem with the touch screen?

In case you want to get in touch with FlyOrDie's technical support, you can do so here.

to get back to you. 

Best regards,
