IE8 problem - solved

[Adam Lyon]

Posting this here in case someone else comes across this same issue.

I'm using the cropper within a content management system (OpenCms),
and version 1.2.1 was working fine with everything except Internet
Explorer 8. No errors were thrown, all the files were being loaded
(including the CSS), the onEndCrop function was being called, but the
UI tool wasn't showing up at all.

The solution in this particular case was to force IE8 to render in IE7
standards mode instead, via a meta tag (or HTTP header).

<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7">

(No trailing slash because this particular document wasn't XHTML.)

I'm guessing the CMS framework was causing whatever issue IE8 was
having, and the above meta tag slapped IE around enough to get it to
work properly.
