Extjs 5 not working in IE9

Hi,

I am working on a project that is developed in Ext JS 3.4 we have migrated to Ext JS 5 recently.But there is a big issue in that. It does not load in IE 9. Yes, no error on console and no UI effect. If I try on IE 10, it works and on Chrome and FF there is no issue.

For more details,

I am using ExtJs 5.0.1 and in my HTML, build/ext-all.js is used from build directory.

As a style sheet,

build/packages/ext-theme-gray/build/resources/ext-theme-gray-all.css

I hope I am not doing wrong.

Waiting for some response so I can go ahead with my current migration job.

Thanks & Regards,

Kanny
