I have an RTD server that feeds Excel with stock market data, and the problem I'm having is that when I open second Excel document, cells that have identical RTD functions as some cells in first document, they won't get updated. Actually, Excel will not call ConnectData() in RTD server for them, it just displays initial values. If I hit F2 to edit them and just confirm with enter, they update. Seems like a problem in Excel itself. Any ideas?
