Question: spectralworkbench fails to recognize camera

Running ubuntu 16.04 can see the output of the spectrometer on VLC so it appears to be working in a fashion at least. I have given spectral workbench permission to use the webcam (the only one on the system) and if I examine my preferences it appears to be the case. However all I get is a black screen. Even downloading it and tryin gto run offline does not seem to help. Any ideas as to what to try next would be most appreciated.

Hi Jeff, Thanks for getting back. I tried both Chrome and Firefox. Similar behavior on both. They are updated as far as Ubuntu is concerned but I suspect that they are not the same level update as windows or apple boxes see. If I use VLC media player the camera does work and I see a spectra, so at least to that level it is working.
Thanks again. Jim
