You can get around that by adding X-UA-Compatible meta tag. There are a few ways to handle this: configure your web server to present the pages in the site as the desired browser mode, have an appliance do it, or manually add the meta tag to all html pages.
In general if you run the IE browser in compatibility mode you can get the page you need to display correctly. Example, using IE10 you can access your portal page then use F12 to see how it renders.
alternately, you may see the 'broken-page' icon in the address bar that will toggle compatibility mode.
That said, you can use:
as the line to add in the device or web server to force the user's browser to see the pages from Lawson as it were IE9, for versions greater than IE9 they are running.Also, you will need to remove the DOCTYPE declaration to force the pages to use quirks mode.
You can see how to configure IIS to do that at Microsoft's MSDN site (http://msdn.microsoft.com/en-US/cc8...kID=204319
As, always, backup before modifying and test before placing into production.
