Uploaded PIE beta4 into root, having read this works where some other versions don't as well. Have tried PIE.htc and PIE.php, both with absolute url and relative. Loading url into browser displays contents of both files so are where the path says they are.

css:
...-moz-border-radius: 10px;
-webkit-border-radius: 10px;
border-radius: 10px; /* future proofing */
-khtml-border-radius: 10px; /* for old Konqueror browsers */
position:relative;
behavior: url(http://www.DOMAIN.com/sg3/PIE.php);
}

I have a message into host re: serving correct content type, but they are a huge host catering to both Win and Mac and it's unlikely that's not right.

Would hugely appreciate any ideas - this is the 3rd site I've had trouble with, after the first one which worked beautifully - same install, same host.

Thanks!

Can you share a URL? Can't really help otherwise...

Of course, sorry!

Also: viewing IEs using Adobe Browserlab (7, 8, don't care about 6!) Using Mac OSX10.6 / FFox3.6.23

For me, in IE7 the container has a shadow and rounded corners and testimonial scale-with-grid has rounded corners. Maybe you should test with something better than Browserlab.

Also for img, you are using ems as a unit and should switch to px: http://css3pie.com/documentation/known-issues/#elements

..and for div.testys you use longhand format and should switch to shorthand.

Thank you, that's very good news! Yes, the css still needs work but I got the bug in my head to get this working - thought I'd isolate it to one instance, which is why the longhand elsewhere (which will be fixed, too, as well as the ems issue).

Hm. I have been using Adobe Browserlab just because I assumed it was reliable - stupid me. Back to browsershots.org? Any other (non$) suggestions?

Meanwhile, I very much appreciate your help

Well we have this thread for tips on solid testing workflows:

Thank you - you've been extremely helpful AND patient, both greatly appreciated!

My secret is being impatient about new versions of PIE I try to eat away as many support tickets as I can! I'm not the best reviewer or debugger, but at least I can help with the most obvious ones.
