I'm trying to get CPST to log errors to my selected Log.txt file, but its not so easy.

When I press Start #1 test, the Log.txt file on my Desktop actually disappears.  It is then no where to be found, including recycle bin.

Strange, my CPST main form looks different from all help file and AGG web page screen shots, as I have a Tabbed lower portion with  Randomly change, Speed, Data source, & Log tabs.

I really need to test my port in question as there is service of a serial port booster involved.

Any suggestions appreciated.
