Thank you for your prompt reply, unfortunately I overwrote the settings I was using to try and get the output in Delimited format.  I will try a re-create the problem and send along the configuration information.

On a related note...things behaved better when I wrote the output to CSV.  Unfortunately, I set the program to create 'daily' log files and CSV output.  For some reason data collection terminated last night at midnight.  I got a few lines of data in the next days log file but no new CSV file was created.  I believe there was an error displayed that said something about an UART overload.  Is there some way to avoid this problem?  I really need a solution that will log data continuously and reliably create daily output files?  I am running the program again today so that I can see if the problem happens again tonight.

I am very new to the suite of AGG software and have run into a couple of problems.  I am currently trying to use the NMEA Logger to parse NMEA sentences from a Garmin GPS and write specific values directly to an Excel file (via Local [Desktop] Database plugin).  When I initially start logging everything works fine, a log file is created as expected and a corresponding Excel spreadsheet is populated with the parsed data. 

However, after awhile things start to go awry with the Excel file.  The first thing I notice is that the Excel file size changes continually and I am unable to move/copy the file...even if I close the COM port the NMEA Logger still reports that local data are being processed (the message updates every 4 seconds)...even though there are no new data coming in???  Its as if the software is caught in some kind of bizzare loop that it can't break out of.  When I did finally manage to restart my machine there was only a small fraction of the expected data in the Excel spreadsheet.

Any ideas on what I might be doing incorrectly???  I am currently trying a test with Delimited output to see if I have the same problem...
