I can not understand why the PIE.htc file connected to round the corners in IE does not work for me. spelled out in styles
#SubPageBanner .bannerButton { border-radius:5px; behavior: url(PIE.htc); }
The main.css and PIE.htc files are in the same folder. In the folder with the styles from the unpacked archive, I transfer only PIE.htc.
The corners are not rounded. What could be the reason?
