Having the same issue-- glad to see I'm not the only one (and sorry you're having the same problem). Hopefully we can figure out what's going wrong soon!
I think I've figured it out? from what I can tell for some odd reason one or two of the "costumes" the default avatar can change to uses the mouse click as a hotkey so the program will switch to that costume and override the actual command input??
I Believe Angel might be right. I've been trying to troubleshoot and what I found was on the Main Page when you open there's the setting button you can click. Then I put all costumes hotkeys to null then when into editing mode and it seemed to do the trick. Hope That helps anyone
