Hi All,
I have been testing a small program for a little while now and recently noticed that the program was not logging any data to my text file. For some reason, if I start out with deleting the file, it will start logging. This has happened to me a couple of times, but I cannot see anything that looks wrong in my code for appending to the text file. If the file does not write, I do not get any error messages of any kind and everything else about it works as expected.
