Had a user today who was experiencing issues submitting an InfoPath form. The original set of error messages made me assume that SharePoint was not set as Local Intranet site (which it wasn't). So I set SharePoint as the local intranet site, updated the user's desktop icon shortcut (to use the https version of the site). And thought, okay, problem solved. Alas and alack, not so! The user entered a form went to submit it and got a different set of error messages. (Unfortunately I didn't think to screenshot the errors and send them to myself so I don't have the exact wording for any of the errors.) The basic message the second time was InfoPath cannot submit the form. I've seen variations of this error before, so I started looking at Compatibility View, and Add-ons. Well, I found the user had IE10 which we recommend our users NOT install as there are known compatibility issues with IE10 and SharePoint 2007 as well as some of our other internal systems. So,
