Thread:Project:Support desk/1.17+ backwards-compatibility with IE7

Hi all-

We're currently running 1.16.5 at my work, and were hoping to update to 1.20 soon for various reasons (one being the CKEditor extension for our many, many Wikitext-hatin' users).

Unfortunately, statistics show that the vast majority of our users are running Internet Explorer 7. They're slowly deploying IE8 (srsly), but it'll be another year or more before everyone has that version. Since we have no control over what browsers our users use (for example, Chrome is installed on every desktop but not everyone uses it), we have to make our products backwards-compatible.

I've upgraded our staging version to 1.20, and it seems to run OK on IE7, but the big issue is that anything jQuery-related doesn't want to play nicely -- for example, switching between tabs on the Preferences pages just doesn't work at ALL.

Are there any tips/tricks on what areas of the newer MediaWiki versions that can be altered to work with IE7? If there are only a few things I could fix, then it'd be a huge help toward pushing the upgrade so we're no longer in the stone ages.
