Error saving waveform: "Can not set datarecord duration of EDF file"

Hello,

DSRemote is working fine for controlling a DS6062 oscilloscope, displaying waveforms, etc. However, every time I try to save a waveform I get the error: "Can not set datarecord duration of EDF file". A zero-length file is created. Any suggestions?

DSRemote master was compiled using Ubuntu 18.04: sudo apt-get install g++ make git-core qtbase5-dev-tools qtbase5-dev qt5-default.

The oscilloscope firmware was updated to latest version (00.02.00.SP5).

Thank you for your work on this software.
