excel not appearing as a tab on taskbar when demantra worksheet is exported

 hello,

when we export a demantra worksheet (current combination or entire view), once the export is complete the excel shows up as a tab on the desktop's task bar and glows .This is not happening anymore.Are there any settings that control this feature?In the absence of this we have to navigate to the folder on the desktop where the excel was saved .Otherwise if this feature is working we can directly click on the excel icon that appears on the taskbar and that opens the worksheet.

Thanks

Rahul
