If you press the export to file icon and
the save as dialog is not displayed it means that there is a
current trend export still being processed. To completely export
the data to a file can take several seconds, so if you export data
to a file and then immediately try to export more data the export
function will not allow you until the first export is completed. It
takes several seconds to complete because Citect is a fully
preemptive system, and Citect is allowing you to continue without
waiting for the data to be exported to the file. Other single
threaded applications would display the hour glass until the data
export was complete, but as Citect is multi threaded you can
continue to do other operations while the export is in progress.
