First of all: Thank you very much @senshu for sharing your work with the world! I created a nice presentation test so fast and I am truly amazed!
Sadly, tomorrow nothing works anymore and I don't know why. I created a test presentation yesterday and everything worked very good. But today, no test presentation is shown properly in any browser and Sozi does not see SVG files to load.
I checked if there had been updates from Windows in the meantime, but there weren't any.
Since Sozi is being run from the folder itself, I cannot "reinstall". Any suggestions what I could try/check?
