I use Chrome on my work computer primarily, but our main ERP system (which was implemented less than 2 years ago) REQUIRES IE6. It will not work on IE7, IE8, IE9, Chrome, or anything else. Various bugs crop up if you try.
I ask, who in their right mind spends hundreds of thousands of dollars on an ERP system that integrates with a browser already several years out of date?
So, for that reason, not only am I stuck using IE in some cases (there are also some online reporting websites that require IE), but I am stuck on the oldest version still in use. Ugh. Triple ugh.
And the worst part is, we can never update to Windows 7 until the ERP system is replaced, which probably won't be for another decade or so.
