Router down and I need to plug ISP's directly into the PC's but I am getting a weird problem. When I plug the backup ISP into my Vista PC, FreeStockCharts runs fine. When I plug the backup ISP into my W7/64 PC, I can't run FreeStockCharts But if I plug my main ISP into the W7 PC or the Vista PA FreeStockCharts runs fine So my W7 PC runs FreeStockCharts with data from the main ISP but the same PC won't run FreeStockCharts with data from the backup ISP. But my Vista PA will run FSC using either my backup ISP or the main ISP. How can that be so? It is only FreeStockCharts that is affected this way and all other charting sw is fine. I am running with only MS Essential for firewall. I need to order a replacement router so any suggestions appreciated.
