Don't have the answer to your question about your machine but you might post on the Vintage Sewig Machine Shop where you can get the right answer.
I thought it was just me on the pages loading. I get the same half page and that darn circle. Then my page dims and I have to hit Backspace to take me "out" of the page. I also get a lot of "server cannot be located". This doesn't happen on my other sites. I'm running IE7 and Windows 7.
