Answer 1

Be aware that certain conditions can force Internet Explorer to display pages in a document compatibility mode different from the one specified in the webpage. These include, but are not limited to, the following situations:

• Compatibility View is enabled for the page.

• The page is loaded in the Intranet zone and Internet Explorer is configured to use Compatibility View for pages loaded from the Intranet zone.

• Internet Explorer is configured to display all websites in Compatibility View.

• Internet Explorer is configured to use the Compatibility View List, which specifies a set of websites that are always displayed in Compatibility View.

• The webpage encountered a page layout error and Internet Explorer is configured to automatically recover from such errors by reopening the page in Compatibility View.

From this we can derive your running a site on your local intranet, ie 7 can't turn off this of the rendering as in ie8 you can stop local intranet sites being rendering in compat mode.

file:// essentially local host

http:// through your local server

UPDATE:

Okay apologies IE has numerous problems running on the intranet, IE8+ is the issue above as you mentioned IE7 doesn't use compat mode it has quirks and standard. Knowing microsoft though they may have messed it up in one of the ie7 patch updates but I hate assumptions so if someone knows please let me know.

To resolve the issue I am afraid I can't give you a software level solution or a hardware change. If its always going to be an intranet site then I recommended upgrading network browsers to ie8 minimum.

I do have a html, css fix however(i know this is not what you want):

It doesn't seem to like [type="buttons"] using display:block;.
