A problem keeps recurring in my LimeSurvey 3.0 installation on my server. Every time I invoke a new survey group, the Limesurvey application hangs. While I can create new surveys and there don't seem to be any other functional issues, I can't organize my surveys under groups. Is this something that others have encountered? Is there a workaround? I've got 30 surveys at this point and I'm supporting a number of grad students who are working in my lab so that number will increase and it would be helpful to organize the surveys more than just a list.
