I know a lot of you guys are having this drag & drop problem on headspace. Trying to find a fix for days, weeks or even months! I understand coz I can relate to that! Anyway, I found a way to fix it. First, thanks to Michael for his post on downgrading the plugin to 3.6.39:
But that did not work for me. So what I did is after I installed 3.6.39 and activated it, I click the upgrade. And that fixed it..
2. Delete files
3. Install version 3.6.39
5. Upgrade to latest
Hope that helps everyone!
