I think this is working now. After rebooting my PC from yesterday, it now comes up when the browser is maximized. I looked an my IE setting for checking for new versions was set to automatic, so I suspect it was caching it from prior to chainging the cfg file. It looks like changing the cfg file worked. I've changed my IE setting to check for new versions every time, so I won't run into the issue again.
Thank you for the response!
