Hi Shane,
so reading your response… can I understand that you are not going to support Ajax navigation in calendar for Internet Explorer 7 and 8? I think it’s a big mistake and can’t believe it.
What “modern ajax calls” is the calendar using? I can see a lot of other calendars with Ajax navigation working fine in IE 6, IE 7 and IE8.
I am really happy with Events Calendar plugin and hope it is a bug and can be fixed.
I have recorded an screencast showing the error:
