>yes, Can you paste some code? I remember I have the problem before I just cant pin point where its is, I assume some part of the Browser setting , and in ASPX code somewhere in the response.content-type if Im not mistaken

I just tried to open the ReportViewer.ASPX file in my IE 7.0, and it opened just fine in the Adobe Reader.

so........... I figure the associations or IE settings on her PC must be out of whack....

which ones should I look for first?

Thanks!
