When I put a css style in separate file, e.g.: WEB-INF/view/module/%MODULE_ID%/resources/css/style.css, then it doesn't load in IE9.
The error is caused by: "SEC7113: CSS was ignored due to mime type mismatch". This means, that OpenMRS webapp configuration doesn't set mimetypes properly in modules' resources directory. This bug affects all modules that have separate .css files.
What will fix this? Setting proper mimetypes in modules' resources directory.
The fixing code should be backported to all OpenMRS supported versions (1.6, 1.7, ...)
