Spectrum does successfully scan initially once the sdr device is selected. However, changing the settings from its user interface crashes the program on my PC I'm running it from XUbuntu Description: Ubuntu 23.10 Release: 23.10 Codename: mantic When the program starts from a Terminal launcher on the desktop, it writes a config.csv file on the descktop. I found, editing this file on the desktop allows Spektrum settings such as startFreq and stopFreq to be set. My copy of Spectrum appears to read successfully from config.csv file on the desktop during startup. However. if I change a user option such as startFreq using the Spectrum graphic interface, the scanning hangs very shortly afterwards. The program is apparently looking for a config.csv file located in /usr/share/spektrum/ I suspect there is an issue about which path is used to access the config.csv The Text is printed to the terminal window when the crash occurs is as follows.

Copying the config.csv file from the desktop to /usr/share/spektrum/ stops the program crashing but then the program still seems to use the desktop version at start up.
Thanks for all your work making this incredibly handy piece of software.
