Subject: Filenames "aux.prg" and "prn.prg" cause errors or application lock up

Symptoms
After adding a new program called "aux.prg" or "prn.prg" to the current project, clicking OK will cause errors or application lock up.  This is because "aux" and "prn" are special files in Windows.

Causes
This is caused by a conflict with Windows built in file names.

Remedy
Use a different file name.

Status
This problem was fixed in version 3.5.0.
