OSWeb experiment problem in fullscreen
I'm preparing a face rating experiment in OsWeb.
the canvas object with picture, buttons for ratings scales is all programmed in javascrit.
When i execute the experimen not in fullscreen everithing goes ok.
When i execute in fullscreen, the first question is ok but all the rest are shifted to the bottom left and some elements disappear.
Any suggestion how to resolve the problem?
