For an existing web application that works fine in Google Chrome, I need help getting it working on IE 8,9, and above. I've applied the Google IE Shim, but it's not getting me all the way there. The site uses Bootstrap, Leaflet web mapping, and HighCharts. It's a single page application. Because of company policies, I can't share backend code with you, but if you examine the site, and make recommendations, I'll make the changes and we can check the results. TO ALL BIDDERS: Please give me some information in your bid description that shows you have experience and skills in troubleshooting these kind of issues. Automatic and generic bids are not likely to be awarded.
