problems with iframes?

I'm passing an url parm to 2 iframes that load within a third iframe. They seem to load quickly enough and the pages in the iframes render fine but the status meter in the status bar never completes. It gets to about 4 bars and then stalls there. The message in the status bar, however, states "Done". My code is quite simple and I am fairly sure there are no problems with it. Perhaps I can just ignore this. I guess what I am wondering is has anyone out there had any problems with calling/loading iframes dynamically? Cheers, Dan
