I have been working on an old system that uses "RadControls for ASP.NET AJAX Q3 2010 NET 40" where the controls are suddenly not working for IE9 only. The system works perfectly in Firefox and IE8, but in IE9 today (yesterday it was fine!) it suddenly won't work in any IE9 I can test it with. I've tried rebooting machines, clearing cache, rebooting web servers: it's only IE9. It's almost as if Microsoft have released an update that has wrecked it.
In the developer tools for IE9, it's saying this:
SCRIPT5022: ASP.NET Ajax client-side framework failed to load.
Default.aspx, line 90 character 34
SCRIPT5009: 'Sys' is undefined
Default.aspx, line 139 character 1
SCRIPT5009: 'Telerik' is undefined
Default.aspx, line 848 character 6
SCRIPT5009: 'Telerik' is undefined
Default.aspx, line 1145 character 1
But in Firefox, there's no whiff of there being any errors whatsoever and the thing works perfectly. Works fine in Chrome 17, as well.
What could be causing this sudden strangeness in IE9 only?
Thanks.
