I'm getting some strange behavior with xlights when I try and select and drag my mouse over multiple effects to select them. For any new sequences I create I am unable to do a group selection with the mouse. I can add them one by one by holding down the control key. What is strange is that when I open up my existing sequences I can drag my mouse over the effects and select a group of them. So somehow xlights is preventing any new sequences from doing a group selection with the mouse. I have both a PC and Mac and they do the same thing, so it seems like there is something in my main directory that is causing the problem. Any idea how to resolve this?
