Until recently, when I'd click "Refresh All," my spreadsheet would update essentially immediately. (I have only about 20 cells that use MarketXLS, all invoking only LastTrade_PriceOnly.) Now it takes around 10 seconds, and I can watch in the status bar as it says "Calculating (8 Processor(s))" and shows the percentage progress. I'm not doing anything where seconds matter, but waiting around for my spreadsheet to update is irritating. Do you know why MarketXLS is suddenly so slow? Could it have to do with a recent version update?
