PIE works on XP, but not on Windows 7
I have a web site which uses PIE behavior in CSS. It works in IE8 on Windows XP, but not in IE8 on Window 7. It seems that on Windows 7 IE8 doesn't even load the PIE.htc file.
XP: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; .NET CLR 2.0.50727)
Win7: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; WOW64; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; MS-RTC LM 8)
Any ideas how to fix that?
