Sorry if this is not the right place, didn't see a support option in the Simon menu.
The licenses window has the checkboxes overlaid with the text, so that it is not usable.
This site is designed to take advantage of CSS. If you are seeing this, CSS must not be available or enabled in your browser. Everything should still work, but won't be as pretty. :)
Re: bug: license window garbled
Are you using a localized edition of Simon? Perhaps a screenshot would help clarify the problem.
