IE 7 and Document Map is Blank

All,

I have a report with a document map and when I run the report through
IE 7.0, the Document Map is blank. Running that same report through IE
6.0 and it is fine.

Both instances are run against the same server via Report Viewer so
there is no difference other than the client IE version.

Anyone know of a work around for this?

Thanks,
Sherry

I have the exact same issue. Anybody has a solution?
