When an Embedded Worksheet Doesn't Work

You probably know that you can embed an Excel spreadsheet into another application and then launch Excel from that other application by double-clicking the embedded spreadsheet. On occasion, the other application ignores the double-click. When this happens, don't panic, because the situation is probably easy to correct.
Excel will ignore requests from other applications if you've set the Ignore Other Applications option. You'll find this option by choosing Tools, Options and then clicking the General tab from within Microsoft Excel. If this option is selected, Excel won't automatically launch when you double-click an embedded Excel object in another application.
To correct the problem, simply select the option and close Excel. The next time you call Excel from an embedded object, everything should work just fine.
