Query Wizard - slow response moving thru tabs

The Query Wizard is ridiculously slow when I move from  tab to tab, e.g., from Welcome to Fields, from Fields to Column Headings, etc. It takes more than a minute for the next tab to display; I actually go and do something else while waiting. Once the query has been built, the actual data retrieval is very fast.

I'm running S3 Addins ver 9.0.3.1387 and Excel 2007 SP3 all on Win 7. I'm the only Win 7 user in our organization so I can't compare performance with anyone else here.

Has anyone see this? Any thoughts on how to resolve?

Thanks.
