Silverlight preview problems

Hello,

Hope this isn’t too lame of a question to ask on such a technical forum, but thought I’d give it a go.

I’m reworking a Deep Zoom Composer layout in Expression Blend 2 and Visual Web Developer 2008 Expression. After building the solution and building the website in Visual Web, the generated page in the web browser looks great when I run the debug (F5). I save the solution, etc.

Later, when I re-open the hml in by browser, the solution and my changes are not shown. Any suggestions as to why, and what I can do about it?

Thanks in advance
Cam
