I have created a layout with rounded corners which works in firefox/chrome. When I open the site in IE the rounded corners don't work cause it is CSS3. Now I have to tried: http://www.htmlremix.com/css/curved-corner-border-radius-cross-browser http://fetchak.com/ie-css3/ http://css3pie.com These sites provide .htc files which should create rounded corners in all browsers. This works locally(outside of mendix) but doesnt work in a mendix project. How can I fix this?
